TPS62745DSSR Description

Short technical summary and product information.

The TPS62745DSSR from Texas Instruments is a synchronous step-down converter designed for ultra-low power wireless applications. It features a wide input voltage range of 3.3V to 10V and can deliver up to 300mA of output current. With a typical quiescent current of only 400 nA, this converter is optimized for battery-powered devices where energy efficiency is critical.

 

This device offers high efficiency, reaching up to 90% with load currents greater than 15 µA. It supports 16 selectable output voltages ranging from 1.8V to 3.3V, providing flexibility for various power requirements. The TPS62745DSSR integrates an input voltage switch and a discharge function at VOUT, along with an open-drain Power Good output.

 

Packaged in a compact 12-WSON (2x3 mm) format, the TPS62745DSSR is suitable for space-constrained designs. It operates within an ambient temperature range of -40°C to 125°C and is mounted using a surface mount technique. The converter utilizes a Buck topology and operates at frequencies up to 2.5MHz, supporting efficient power conversion with low output ripple.
