DC-DC Controller (External Switch) Adjustable, up to 3A, 95% Efficient Step-Down Controller, 20uA, SOT-23 DC DC Cntrlr Single-OUT Step Down 1.8V to 6.5V Input 6Pin SOT-23 T/R
The TPS64202DBVR is an non-synchronous Step-Down Controller ideally suited for systems powered from a 5 or 3.3V bus or for applications powered from a 1-cell Li-Ion battery or from a 2- to 4-cell NiCd, NiMH, or alkaline battery. This 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 20µA quiescent current.
