Noteworthy Non-linear Hysteresis Control Method As a DC/DC Converter Control Method

"Bottom detection comparator method" is the best method for the power supply to the Core of system LSI with the severe demand

of the power-supply voltage accuracy, to the memory, to the power-supply specification with the large I/O voltage difference.

MB39A214A, MB39A202A achieved a low output ripple operation by adding our improved new circuit to a past bottom detection

comparator method.

Although the conventional mainstream DC/DC converter control methods were voltage control or current control, recently the non-linear hysteresis control method attracts attention along with the lowering the voltage of the power-supply voltage of system LSI. Since 2005, FUJITSU has shipped more than 100 million DC/DC converter ICs that adopt the bottom detection comparator method (a type of hysteresis control method), mainly to the commercial market.The reason why this method attracts attention is an excellent point in "High-speed load transition response characteristic" and "Low on-duty operation with stability". Moreover, the power supply design is easy.

Outline of Bottom detection comparator method

The bottom detection comparator method compares with the comparator of a feedback voltage and a reference voltage always, and keeps the output voltage by off-time control and the fixed on-time.Therefore, when the output voltage changes by a rapid change in the load, this method rapidly stabilizes the output voltage by controlling the off-time and changing the switching frequency. (Refer to Fig.2)This method is best for the system that the low voltage power supply is especially necessary, because the voltage stability is more excellent than the voltage control and the current control method using a conventional error amplifier.In addition, this method can reduce the output capacitor for smoothness, because the voltage stability is excellent. This point contributes to the part cost reduction in the entire set.

Feature 1: High-speed load transition response characteristic

In the voltage control and the current control method, the phase compensation circuit is necessary to prevent the oscillation of the DC/DC converter output. This circuit is a circuit to adjust the phase delay of a feedback system and the gain of the error amplifier.The bottom detection comparator method has little phase delay for feedback-loop-system. This method uses a comparator without an error amplifier, it therefore requires no phase compensation circuit.Therefore, it is possible to greatly shorten the period of power supply design, without preparing a special measurement environment and without requirement to adjust the circuit at the power supply design.

Feature 2: No phase compensation circuit required

The bottom detection comparator method does switching control by fixing the on-time and by controlling off-time.It is therefore possible to supply stable output voltage without becoming unstable, even under conditions of large input-output voltage difference.Direct conversion is easy to the low voltage power supply from the first power supply. Therefore, the energy-saving effect by the decrease of the conversion loss can be expected compared with the case to use the second or third power supplies.

Feature 3: For low on-duty (Secure on-time switching control)

An optimal IC for power management systems in portable devices with one built-in channel of DC/DC step-down converter for digital

circuits and one built-in channel of low-noise LDO for analog circuits. It can also be used in products adopting one cell of Li-ion

battery as the power supply. Two power management systems in a 3.0mm×3.0mm, 10-pin package and the built-in switching FET

enable the construction of a power management system at a low BOM cost. There are four versions of the fixed output voltage in

the LDO block.

The MB39C022 Series are optimal power management ICs for the construction of systems for ARM architecture-based system ICs, GPSs, and portable TVs.Low-noise LDO is demanded for power supplies for RF, PLL, and analog functions. This product is a 2-channel power management IC combining a DC/DC converter and a low-noise LDO. It is useful in electronic devices with mixed analog and digital components.

PFM/PWM control circuit (CH1)The frequency (2.0MHz) set up by the built-in oscillator (square wave oscillating circuit) is used to enable synchronous rectification operation of the built-in P channel MOS FET and N channel MOS FET. PFM operation is executed under light loads.

Iout comparator circuitThis circuit detects the current flowing from the built-in P channel MOS FET to the external inductor (ILX). It compares VIDET obtained by I-V conversion of the ILX peak current and the Error Amp. output to turn OFF the built-in P channel MOS FET through the PFM/PWM logic Control circuit.

Error Amp.(CH1) phase compensation circuitThis circuit compares the VREF reference voltage and the output voltage. The phase compensation circuit of this product is realized by externally attaching a feedback resistor and a capacitor for phase compensation to the FB terminal.

LDO circuit (CH2)The built-in low-noise LDO can output currents up to 300mA. A capacitor is required on the VOUT2 pin for stability.Table 1 presents the output settings and power supply rejection ratio (PSRR) of the LDO block of this product.

Power on Reset (POR) circuitThis circuit monitors the VO1 terminal voltage (CH1 output voltage) via the FB terminal. The POR pin has open drain output. It is normally used in pull-up with an external resistor. While the POR pin reaches H level when VO1 reaches the set output voltage, it is set to L level when the output voltage drops due to over current and so forth.

VREF circuitIt generates a highly precise reference voltage using a BGR (band-gap reference) circuit.

Protection circuit The over-temperature protection circuit (OTP) stops the entire output operation at CH1 and CH2 when the junction temperature reaches +135°C. It restores CH1 and CH2 to normal operation when the junction temperature drops to +110°C. Since the PFM/PWM control circuit adopts the current mode architecture for its control method, the current peak value is constantly monitored and controlled.

Control circuitTable 2 presents the function control by EN1 and EN2 pins.Figure 1 presents the block diagram for this product.

We offer an evaluation board (Photo 2) to simplify the single unit evaluation of this product.

We plan to successively introduce product versions that offer fixed output voltage of the LDO block in the future. We will continue devel-opment to meet our customer needs, aiming to address further minia-turization and cost reduction.

Figures 2 and 3 present application examples. This product is optimal for the following applications: - Portable applications - GPS, PND - MP3, PMP - Portable TV, USB dongle (CMMB, DVB-T, DMB-T) - SMART-PHONE, etc.

Power Management IC for Portable Instruments 6MHz Synchronous Rectification Buck Boost DC/DC Converter IC

MB39C326

This product is a highly effective and low-noise 6MHz buck boost DC/DC converter IC that has been developed for mobile instruments using a one-cell lithium-ion battery. With its high operating frequency (6MHz), the inductor size can be significantly reduced compared with existing 2 to 3MHz products, and the board area of the power part can be downsized by half (Figure 1). Since our unique buck boost circuit switches automatically between the voltage increasing operation and the voltage decreasing operation against input voltage, power is supplied stably even when the inputting battery voltage decreases, and the system driving time can be expanded through the effective utilization of the remaining power in the battery.

An evaluation board (Photo 2) that enables easy evaluation of the product unit is available.

DC/DC control methodThe internal oscillator (square-wave oscillating circuit) operates the synchronous rectification of the built-in P-ch MOSFET and the N-ch MOSFET at the predetermined frequency (6MHz). Our unique circuit technology allows seamless switching between the voltage increasing mode and the voltage decreasing mode, thereby realizing high-efficiency operation.

Overcurrent protection functionThis function controls the current to prevent higher output current than the setting from flowing. Also, when the output current reaches the current limit value, the output voltage starts dropping. The overcurrent protection function detects current flowing from the built-in P-ch MOSFET (overcurrent protection function) that connects the VDD terminal to the external inductor. The current limit value can be selected from three values, according to the XPS terminal and the ILIMSEL terminal theory, as shown in Table 2.

Output voltage setting functionOutput voltage setting by FB splitting resistance (constant output)

Output voltage setting by the VSELSW terminal (selecting an output from two values)Two output setting voltages can be switched between by inputting the VSEL terminal signal (Figure 3).- VSEL = L - VSEL = H

Output voltage setting by signal input (output is arbitrarily variable)By inputting DAC signals, the output voltage can be changed arbitrarily according to the setting formula (Figure 4).

Relation between output and DACFigure 5 shows the relation between the output and the DAC when the settings are R1 = 620kΩ, R2 = 110kΩ, and R3 = 330kΩ.

Operation example of RF power amp (PA) (Figure 7)When a PA has low transmitting and output power, and a conventional battery is directly connected to it, excessive energy is supplied to the PA. By inserting the DC/DC between the PA and the battery, the voltage supplied to the PA (Vout) can be changed and adjusted according to the transmitting and output power, and the power efficiency can be improved accordingly.

Functions

This product is ideal for the following applications: - Mobile phones, smart phones, digital book terminals, and PDAs - Products with one-cell lithium ion batteries (Figure 6) - RF power amps (PAs) - RF-PC cards

ApplicationThis product is a power management IC for portable instruments that has a highly effective buck boost DC/DC converter, which expands the available input voltage range. It can be loaded on a small 2.15mm × 1.94mm package(Photo 1), and can configure a power system with a small footprint at low BOM cost, with its built-in switching FET. By inputting signals such as DAC, it can control the output voltage value dynamically.
