This is a 20A Communication or Enterprise Storage ASIC Adaptive Voltage Scaling (AVS) power supply using the TPS53819A PMBus PWM controller. The design enables high power density, PCB layout flexibility and ease of test and design for AVS using the PMBus interface and the Vout Adjustment and Margining Commands. The use of the external Power Block enables flexible PCB placement and upgrade to newer power blocks if needed.
