TPS54325 - Texas Instruments

TPS54325 3-A Output Synchronous Step-Down Switcher

The TPS54325 device is an adaptive on-time DCAP2™ mode synchronous buck converter. The TPS54325 device enables system designers to complete the suite of various end equipment’s power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS54325 uses the DCAP2™ mode control which provides a ver.
