LED Lighting Reference Design CookbookHelping You Solve Your Lighting Design Challenges

The LED Lighting Reference Design Cookbook is designed to provide you with a valuable tool to help you solve your lighting design needs. Customers seeking the latest in innovative and affordable LED lighting solutions can benefit from TI’s broad product portfolio of AC/DC, DC/DC, LED drivers, power management devices, wireless and wired interface control and embedded processors.

Designers have the option of not only controlling the power stage, but regulating LED currents as well, eliminating the need for multiple components and reducing system cost. Systems can be designed to accurately control voltage and current regulation for precise light intensity and color mixing, temperature monitoring to prevent thermal runaway, intelligent/adaptive dimming, and fault detection (over voltage/current, blown string). Communication with external systems is also possible via power-line communication (PLC), wireless technology or interfaces.

LED lighting designers are challenged with meeting their efficiency and reliability goals faster in advanced lighting designs. TI’s lighting portfolio is helping designers achieve their goals at a faster rate.

prevents dangerous output voltages from occurring during open-string conditions. A current-sense amplifier reduces the sensing resistor’s power dissipation, thus increasing overall efficiency. The internal reference voltage of the operational amplifier achieves excellent LED-current regulation versus output power and input voltage. The PMP4501 achieves high efficiency (90% peak), high power density and a high power factor. The reference design protects against scenarios with open and short LED strings, and the control stage is a simple and robust design.

UCC28810 PMP3976 - 100-W, Offline PFC SEPIC LED Driver The PMP3976 circuit shown below was designed for a commercial LED lighting fixture. The SEPIC topology has the advantage over a flyback converter in that it clamps the switching waveforms on the power semiconductor, allowing the use of lower voltage and hence more efficient parts. This provides an estimated 2% improvement in efficiency in this application. Additionally, there is less ringing in the SEPIC, making EMI filtering easier.

TPS63000 PMP3038 The TPS63000 provides a power-supply solution for products that use a two- or three-cell alkaline, NiCd or NiMH battery, or a one-cell Li-Ion or Li-Polymer battery. The buck-boost converter is based on a fixed-frequency PWM controller that uses synchronous rectification to obtain maximum efficiency. The maximum average current in the switches is limited to a typical value of 1800 mA, and the converter can be disabled to minimize battery drain. During shutdown, the load is disconnected from the battery. The device is packaged in a 10-pin QFNPowerPAD™(DRC)packagemeasuring 3 x 3-mm.

During operation, the VBAT drops below the Vf of the LED, and the TPS63000 automatically switches from buck mode to boost mode to create the constant current needed for the LED. The TPS63000 can boost from voltages as low as 1.2 V. A switch that brings R4 into or out of the feedback loop provides a dimming mechanism for the flashlight to toggle between 300 and 600 mA.

single-reference current control and universal dimming (via AM or PWM) for all LEDs. The reference design effectively drives a large number of LEDs connected in series, but the voltage on the LED strings is safe (low) and isolated from the AC line. The multistring architecture is more cost-effective than an architecture with a constant voltage plus a buck stage for each LED string. The LED-driver architecture is readily scalable to very high power levels. Excellent LED current matching between strings is achieved with this architecture. The UCC28810EVM-003 achieves high efficiency (91%), high power density and a high power factor. The control stage is a simple and robust design, and the EVM protects against scenarios with open and short LED strings.

DescriptionThe TPS40211EVM-352 evaluation module (EVM) is a fixed frequency, (300 kHz), non-synchronous boost converter providing fixed 700-mA output at 20 V to 35 V from a 8-V to 18-V input source. The EVM is designed to start up from a single supply, so no additional bias voltage is required for start-up. The module uses the TPS40211 Non-Synchronous Current Mode Control Boost Controller with integral N-channel FETdriver.TPS40211EVM-352 is designed to use a loosely regulated 12-V (8 V to 18 V) source to produce a regulated current driver at 700 mV for constant current loads such as high-brightness LEDs. TPS40211EVM-352 is designed to demonstrate the TPS40211 in a typical LED Driver for 6 to 10 LEDs while providing a number of test points to evaluate the performance of the TPS40211 in a given application. The EVM can be modified to other input voltages or output currents by changing some of the components.

TPS62260LEDResidential and commercial lighting can take advantage of the additive color mixing of red, green and blue LEDs. This reference design demonstrates how to remotely manage the color output of an LED lamp with a low-power wireless controller. The color is generated by three LEDs (red, greenandblue).AnMSP430™ultra-low-power microcontroller controls the brightness of each LED with constant current generated by three TPS62260 buck converters, one for each LED.

The color look-up table takes the form of an array stored in the MSP430. Whenever the rotary encoder is turned, new red, green and blue values are read from the array and used to generate the three PWM output signals. Currently 252 values are stored, which can be changed if desired. A decimal value of 100 switches the LED off, and a value of 65535 produces a mark-space ratio of 100%. When the 5-V supply is applied, the design goes into a demonstration

TMDSIACLEDCOMKITThe AC input multi-string lighting kit accepts universal AC input and can control up to six LED strings. The AC input is converted to DC and then an onboard MCU converts this DC voltage to the string voltage through an isolated LLC DC/DC. The string voltage is adjust-able to make it easy to use one design to cover many different requirements for string lengths, types of LEDs and number of strings. LEDs can be dimmed either through PWM to keep constant color or through the adjusting string voltage. In addition, it is a communica-tions/control platform and has power line communications, DALI, DMX-512 andlowpowerRFlightingcontrol.
