TPS5432 - 700kHz Synchronous Step-Down Converter

General Description

The TPS5432 is a 6V, 3A, low Iq, current mode, synchronous monolithic buck converter with integrated MOSFETs.

The TPS5432 enables small designs by integrating the MOSFETs, implementing current mode control to reduce external component count, reducing inductor size by 700kHz switching frequency.
