TPS53114 - Texas Instruments

TPS53114 Single Synchronous Step-down Controller

The TPS53114 is a single, adaptive on-time DCAP2™ mode synchronous buck controller. The TPS53114 enables system designers to complete the suite of various end equipment's power bus regulators with cost effective low external component count and low standby current solution. The main control loop for the TPS53114 uses the D-CAP2™ mode control which provides a.
