TPS65261-1RHBR Description

Short technical summary and product information.

The TPS65261-1RHBR from Texas Instruments is a monolithic triple synchronous step-down (buck) converter designed for efficient power management.

 

This device operates with an input supply voltage range of 4.5V to 18V, making it suitable for various intermediate bus voltages. It offers three output channels with maximum continuous output currents of 3A, 2A, and 2A respectively. The output voltage is adjustable, providing design flexibility.

 

Key electrical characteristics include a wide adjustable clock frequency range from 250 kHz to 2 MHz, enabling optimization for efficiency and component size. The converter utilizes constant frequency peak current mode control. Features such as dedicated enable and soft start pins for each buck, automatic power-up/down sequencing, and output voltage power-good indication simplify application design.

 

The TPS65261-1RHBR is housed in a 32-VQFN (5x5 mm) package, suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C.
