High-efficiency 300 mA synchronous step-down converter — 2.5 V to 6 V input, adjustable output from 0.7 V, in SOT-23 package, ideal for low-power portable systems.
Product Overview
The TPS62200DBVR is a high-efficiency synchronous step-down (buck) converter from TI. It supports an input voltage range of 2.5 V to 6 V, with output voltage adjustable from 0.7 V up to VIN. Maximum output current is 300 mA. At nominal load, the switching frequency is about 1 MHz, and under light load conditions the part enters power-save mode, achieving typical quiescent current around 15 µA. Packaged in SOT-23-5 (DBV), it is ideal for space-constrained and low-power portable designs.
This device is well-suited for systems powered by a single Li-ion cell or 3-cell NiMH/NiCd battery, and also standard 3.3 V / 5 V rails.
