Product Summary
The TPS64200DBVT is a nonsynchronous step-down controller ideally suited for systems powered from a 5-V or 3.3-V bus or for applications powered from a 1-cell Li-Ion battery or from a 2- to 4-cell NiCd, NiMH, or alkaline battery. The step-down controller drives an external P-channel MOSFET allowing design flexibility. To achieve highest efficiency over a wide load current range, this controller uses a minimum on time, minimum off time control scheme and consumes only 20-μA quiescent current. The applications of the TPS64200DBVT include USB Powered Peripherals, Organizers, PDAs, and Handheld PCs, Low Power DSP Supply, Digital Cameras, Hard Disk Drives, Portable Audio Players.
