TPS54428DRCR Description

Short technical summary and product information.

The TPS54428DRCR from Texas Instruments is a 4A synchronous step-down converter designed for efficient power management. It operates with an input voltage range of 4.5V to 18V and provides an adjustable output voltage from 0.76V to 7.0V.

 

This converter utilizes D-CAP2 mode for fast transient response and low output ripple, allowing the use of ceramic output capacitors. It features integrated FETs with low on-resistance (70 mΩ high-side, 53 mΩ low-side) for high efficiency, especially at lower duty cycles. The device includes features like adjustable soft-start, cycle-by-cycle overcurrent limit, and Auto-Skip Eco-mode for improved light-load efficiency.

 

The TPS54428DRCR is available in a 10-VSON (3x3) package and is designed for surface mount applications. Its operating temperature range is -40°C to 85°C.

 

Key electrical specifications include a switching frequency of 650kHz, a maximum output current of 4A, and a typical quiescent current of 0.00095A. It also offers high efficiency, with less than 10µA at shutdown.
