TPS40075RHLR Description

Short technical summary and product information.

The Texas Instruments TPS40075RHLR is a synchronous buck controller with a wide input voltage range of 4.5V to 28V. This device is designed for step-down (buck) topology applications, offering an output current capability of up to 20A and an output voltage range from 0.7V to 23V.

 

Key electrical features include a programmable switching frequency up to 1MHz, a maximum duty cycle of 95%, and a typical quiescent current of 0.0015A. The controller supports synchronous rectification and features like current limit, frequency control, power good indication, and soft start for robust operation. It also includes an internal 700mV reference voltage.

 

The TPS40075RHLR is housed in a 20-VQFN (3.5x4.5mm) package with exposed pad, suitable for surface mounting. The operating temperature range is -40°C to 85°C (TA). This controller is well-suited for applications such as power modules, networking, telecom, and industrial servers where efficient DC/DC conversion is required.
