TPS54528 - Texas Instruments

TPS54528 5-A Synchronous Step-Down Converter

The TPS54528 is an adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS54528 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 TPS54528 uses the D-CAP2™ mode control that provides a fast transient res.
