TPS54A20 Description
The TPS54A20 is a two-phase, synchronous series capacitor buck converter designed for small size, low voltage applications from a 12-V input rail. This topology uniquely merges a switched capacitor circuit with a two phase buck converter. Advantages include automatic current balancing between the inductors, lower switching losses which enable high frequency (HF) operation, and voltage step-down through the series...
