TPS54327 - Texas Instruments

TPS54327 3-A Output Single Synchronous Step-Down Switcher

The TPS54327 device is an adaptive on-time DCAP2™ mode synchronous buck converter. TheTPS54327 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 TPS54327 uses the D-CAP2 mode control which provides a fast transi.
