The TPS54A20 is a two-phase, synchronous seriescapacitor buck converter designed for small size, lowvoltage applications from a 12-V input rail. Thistopology uniquely merges a switched capacitor circuitwith a two phase buck converter. Advantages includeautomatic current balancing between the inductors,lower switching losses which enable high frequency(HF) operation, and voltage step-down through theseries capacitor. Small, low profile inductors usedwith the TPS54A20 significantly reduce total solutionarea and height. An adaptive on-time controlarchitecture provides fast transient response andaccurate voltage regulation at up to 10-MHz operatingfrequency. Fixed frequency operation during steadystate is maintained through the use of a phase lockloop (PLL) to lock switching signals to a referenceoscillator.
