Anpec Electronics APW7035

The APW7035 integrates PWM controller and linear controller , as well as the monitoring and protection functions into a single package , which provides two controlled power outputs with over-voltage and overcurrent protections. The PWM controller regulates the DDR reference voltage (1.25V) or GPU Voltage (2.05V) with a synchronous-rectified buck converter. The linear controller regulates power for Memory Voltage.

GENERAL DESCRIPTION

The precision reference and voltage-mode PWM control provide ±1% static regulation. The linear controller drives an external N-channel MOSFET to provide adjustable voltage. The APW7035 monitors all the output voltages , and a single Power Good signal is issued when the PWM Voltage is within ±10% of the DAC setting and the Linear regulator output levels are above their undervoltage thresholds. Additional built-in over-voltage protection for the PWM output uses the lower MOSFET to prevent output voltages above 115% of the DAC setting. The PWM over-current function monitors the output current by using the voltage drop across the upper MOSFET’s RDS(ON) , eliminating the need for a current sensing resistor. The APW7035A/B/C/D support a TTL 3-input Digital to Analog converter that adjusts the synchronousrectified buck converter output from 1.00V to 3.20V , reference to Table1. − Switching Power for Fixed Voltage (1.25V / 2.05V)...
