TPS40428RHAT Description

Short technical summary and product information.

The Texas Instruments TPS40428RHAT is a versatile DC/DC switching controller designed for high-performance power management applications. This device functions as a step-down (buck) controller, featuring dual outputs and a 2-phase multiphase topology for efficient power delivery.

 

Key electrical specifications include a wide input voltage range of 4.5V to 20V and an output voltage range from 0.6V to 5V, with a maximum output current capability of 40A. The controller operates at switching frequencies between 200kHz and 1.5MHz. It supports advanced control features such as frequency synchronization, phase control, and power good indication. The integrated PMBus interface allows for digital control and monitoring.

 

Designed for surface mount installation, the TPS40428RHAT is housed in a 40-VQFN (6x6) package. It operates within an ambient temperature range of -40°C to 125°C. Additional features include adjustable current limit, dynamic voltage scaling, pre-bias start-up, remote sense capability, and adjustable UVLO thresholds, making it suitable for demanding power system designs.
