General Description

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.
