TPS65250RHAR Description

Short technical summary and product information.

The TPS65250RHAR from Texas Instruments is a versatile three-channel synchronous step-down buck converter designed for high-efficiency power management applications. It supports a wide input supply voltage range from 4.5 V to 18 V, making it suitable for various system voltages.

 

Each converter channel offers adjustable output voltage down to 0.8 V with 1% accuracy. Buck 1 can handle a continuous load of 3 A and a maximum current of 3.5 A, while Buck 2 and Buck 3 support 2 A continuous load and 2.5 A maximum current. The switching frequency is adjustable from 300 kHz to 2.2 MHz, allowing for optimization of component size and efficiency. Features like soft start, adjustable current limit, power good, and reset generation simplify system design.

 

The device is available in a 40-pin, 6 mm x 6 mm QFN (RHA) package, suitable for surface mount applications. Its integrated power transistors and current-mode control with simple compensation circuitry reduce external component count. The TPS65250 also includes a unique storage and release circuit optimized for dying gasp mode, reducing storage capacitance requirements.

 

Applications for the TPS65250RHAR include xDSL/xPON modems, cable modems, power line modems, home gateways, access point networks, wireless routers, and set-top boxes, where efficient and flexible power conversion is required.
