TPS54329E - Texas Instruments

TPS54329E 3-A SYNCHRONOUS STEP-DOWN CONVERTER

The TPS54329E is an adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS54329E 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 TPS54329E uses the D-CAP2™ mode control that provides a fast transient .
