TPS65261RHBR Description

Short technical summary and product information.

The TPS65261RHBR from Texas Instruments is a monolithic triple synchronous step-down (buck) converter designed for power management applications. It operates with an input supply voltage range of 4.5V to 18V, making it suitable for intermediate bus voltages derived from 5V, 9V, 12V, or 15V power rails.

 

This converter features three output channels with maximum continuous output currents of 3A, 2A, and 2A. The output voltage is adjustable, with a feedback reference voltage of 0.6V ±1%. It utilizes a constant frequency peak current mode control and offers an adjustable clock frequency from 250 kHz to 2 MHz. Key features include dedicated enable and soft start pins for each buck, automatic power-up/down sequencing, and Pulse Skipping Mode (PSM) at light loads.

 

The TPS65261RHBR is housed in a 32-VQFN package measuring 5mm x 5mm with an exposed pad for enhanced thermal performance. It is designed for surface mount applications and operates within an ambient temperature range of -40°C to 85°C. The device also includes output voltage power-good indication and input voltage power failure indication for robust system monitoring.
