TPS57040QDRCRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS57040QDRCRQ1 is an automotive-qualified step-down DC-DC converter capable of delivering up to 500mA of output current. It features a wide input voltage range from 3.5V to 42V, with an adjustable output voltage down to 0.8V.

 

This converter utilizes current mode control and operates with a switching frequency adjustable from 100kHz to 2.5MHz. A key feature is its Eco-Mode™ control scheme, which provides high efficiency at light loads by using pulse skipping. The device also includes adjustable soft start, enable functionality, frequency synchronization, and a power-good output.

 

Packaged in a 10-VSON (3x3) or 10-VFDFN exposed pad, the TPS57040QDRCRQ1 is designed for surface mount applications. It operates within an ambient temperature range of -40°C to 150°C (TJ), making it suitable for demanding automotive environments. The device also includes undervoltage lockout (UVLO) and overvoltage protection features.
