input and output matching and internal power detection function and power control loop in GSM mode.

in GSM mode, the internal power control circuit ensures a stable power output, set by the level of VDAC stabilsed to

compensate variations of supply voltage, input power and temperature, with a control range fully compaliant with ETSI

tome mask and power spectrum requirements

in EDGE mode the output power is controlled by the input power. The VREF signal is used to control the efficiency by

controlling the quiescent current of the final RF-statges of both line-ups.

2-2-1. PCF50603 (U400)- Power Management

Eight low-dropout regulators designed specifically for GSM applications power the terminal and help ensure optimal

system performance and long battery life. A programmable boost converter provides support for 1.8V, 3.0V SIMs,

while a self-resetting, electronically fused switch supplies power to external accessories. Ancillary support functions,

such as RTC module and High Voltage Charge pump, Clock generator, aid in reducing both board area and system

complexity.

full control of the PCF50603 and enables system designers to maximize both standby and talk times.

Supervisory functions. including a reset generator, an input voltage monitor, and a temperature sensor, support reliable

system design. These functions work together to ensure proper system behavior during start-up or in the event of a

fault condition(low microprocessor voltage, insufficient battery energy, or excessive die temperature).
