Buck regulator for 300 mA rails
The TPS62200DBVR is a 1 MHz fixed-frequency synchronous buck converter from Texas Instruments, delivering up to 300 mA from a 2.5 V to 6 V input rail. The adjustable output can be set from 0.7 V up to the input voltage, making it a fit for powering low-voltage MCU cores, sensor bias, or auxiliary logic supplies in space-constrained designs.
1 MHz switching with synchronous rectification
Active production in SOT-23-5
The SOT-23-5 footprint is straightforward for two-layer boards and hand-assembly rework.
Industrial temperature coverage
The 300 mA ceiling is a hard limit — derate for ambient above 85°C per the datasheet thermal curves.
