TPS54426PWPR Description

Short technical summary and product information.

The Texas Instruments TPS54426PWPR is a 4A synchronous step-down converter designed for efficient power management. It operates with an input voltage range from 4.5V to 18V and provides an adjustable output voltage from 0.76V to 5.5V.

 

This converter utilizes D-CAP2 mode for fast transient response and low output ripple, allowing the use of ceramic output capacitors. It integrates high-efficiency FETs with low on-resistance (65 mΩ high-side, 55 mΩ low-side) and features Eco-Mode for high efficiency at light loads. The device operates at a 700kHz switching frequency and includes features like adjustable soft-start, power good output, and cycle-by-cycle overcurrent limit.

 

The TPS54426PWPR is available in a 14-HTSSOP package and is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA). Applications include power supplies for digital TVs, networking equipment, and set-top boxes.
