TPS62743YFPR Description

Short technical summary and product information.

The TPS62743YFPR from Texas Instruments is a highly efficient step-down (buck) DC/DC converter designed for ultra-low power applications. It operates with an input voltage range of 2.15V to 5.5V, with the ability to start up from as low as 2.0V. This device can supply up to 300mA of output current, with a variant (TPS627431) capable of 400mA.

 

Key electrical characteristics include a typical quiescent current of 360nA, contributing to its power-saving capabilities. It operates at a frequency of 1.2MHz and features synchronous rectification for improved efficiency. The converter offers selectable output voltages ranging from 1.2V to 3.3V and achieves up to 90% efficiency at a 10-µA output current, making it suitable for light-load conditions.

 

The TPS62743YFPR is housed in a compact 8-DSBGA package, measuring 1.8 mm², with a total solution size of less than 10 mm². This small footprint, combined with surface mount capability, makes it ideal for space-constrained designs. The operating temperature range is -40°C to 125°C (TJ).
