Overview
The TPS60131PWPRG4 is a high-efficiency charge pump DC-DC converter produced by Texas Instruments. This device is part of the TPS6013x family and is designed to generate a regulated 5-V output voltage from an input voltage range of 2.7 V to 5.4 V. It is particularly suited for space-critical, battery-powered applications and requires only four external capacitors to build a complete charge pump circuit. The TPS60131PWPRG4 is optimized for high efficiency over a wide input voltage range and supports up to 300 mA of output current.
