TPS56428RHLR Description

Short technical summary and product information.

The Texas Instruments TPS56428RHLR is a synchronous step-down (buck) converter designed for power management applications. It accepts an input voltage ranging from 4.5V to 18V and can deliver up to 4A of output current. The output voltage is adjustable, providing design flexibility.

 

Key electrical specifications include a switching frequency of 650kHz, enabling the use of smaller passive components. The device features integrated FETs with low on-resistance (68 mΩ high-side, 37 mΩ low-side) for improved efficiency. It also includes features such as Enable, Light Load Efficiency, Power Good, and Soft Start.

 

The TPS56428RHLR operates within a temperature range of -40°C to 85°C. It is available in a 14-VQFN (3.5x3.5 mm) package, suitable for surface mount applications. The converter utilizes the D-CAP2 control mode for fast transient response and supports ceramic capacitor usage.

 

This component is designed for applications requiring efficient voltage conversion. Its adjustable output and robust feature set make it a versatile choice for various power supply designs.
