TPS65250RHAT Description

Short technical summary and product information.

The TPS65250RHAT from Texas Instruments is a high-efficiency, synchronous step-down buck converter with three integrated converters. It supports a wide input supply voltage range from 4.5 V to 18 V, making it suitable for various power systems.

 

This device offers adjustable output voltages down to 0.8 V with 1% accuracy. Buck 1 provides a continuous loading of 3 A, while Buck 2 and Buck 3 each handle 2 A. The maximum current capabilities are 3.5 A for Buck 1 and 2.5 A for Buck 2 and 3. The switching frequency can be adjusted externally from 300 kHz to 2.2 MHz, and it supports external synchronization.

 

Key features include adjustable current limit, enable/sequencing pins, soft-start pins for controlled startup, and a power good/reset generator. It also incorporates a unique storage and release circuit optimized for dying gasp mode applications. The TPS65250RHAT is available in a 40-pin VQFN package (6x6 mm).

 

Applications for the TPS65250RHAT include xDSL/xPON modems, cable modems, power line modems, home gateways, access point networks, wireless routers, and set-top boxes.
