TPS54426RSAR Description

Short technical summary and product information.

The Texas Instruments TPS54426RSAR is a highly efficient synchronous step-down DC DC switching regulator designed for a wide range of applications. It supports an input voltage range from 4.5V to 18V and can deliver up to 4A of output current. The device features an adjustable output voltage, a switching frequency of 700kHz, and integrated FETs for optimized performance.

 

Key features include light-load efficiency, power good indication, and adjustable soft-start. The D-CAP2 mode enables fast transient response and allows the use of ceramic output capacitors, contributing to low output ripple. The regulator is housed in a 16-QFN (4x4) package, suitable for surface mount applications.

 

This converter is well-suited for low-voltage systems, including digital TV power supplies, networking equipment, and digital set-top boxes. Its integrated solution simplifies design and reduces component count.
