TPS54328 - Texas Instruments

TPS54328 3-A Synchronous Step-Down Converter

The TPS54328 is an adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS54328 enables system designers to complete the suite of various end-equipment power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS54328 uses the D-CAP2 mode control that provides a fast transient resp.
