TPS54040ADRCR Description

Short technical summary and product information.

The Texas Instruments TPS54040ADRCR is a 0.5A, 42V step-down DC-DC converter designed for efficient power management. It supports an adjustable output voltage and operates within a wide input voltage range of 3.5V to 42V.

 

Key electrical specifications include a maximum output current of 500mA, a switching frequency adjustable from 100kHz to 2.5MHz, and a typical quiescent current of 116 µA. The device features a 200 mΩ high-side MOSFET and an internal voltage reference of 0.8V. It offers adjustable UVLO voltage and hysteresis, along with features like overcurrent protection and power good output.

 

Packaged in a 10-VSON (3x3) or 10-VFDFN exposed pad, the TPS54040ADRCR is suitable for surface mount applications. Its operating temperature range is -40°C to 150°C (TJ). The converter utilizes a buck topology and current mode control, with no synchronous rectifier.

 

This device is supported by WEBENCH® and SwitcherPro™ software tools, aiding in design and simulation. It is also available in MSOP-10 packages.
