TPS65263RHBT Description

Short technical summary and product information.

The TPS65263RHBT from Texas Instruments is a versatile triple synchronous step-down (buck) converter designed for power management applications. It features I2C controlled dynamic voltage scaling (DVS), allowing for programmable output voltages ranging from 0.68V to 1.95V in 10mV steps. The device supports an input voltage range of 4.5V to 18V and delivers continuous output currents of 3A, 2A, and 2A across its three channels.

 

Key electrical characteristics include a fixed switching frequency of 600kHz, a typical quiescent current of 0.00074A, and a maximum duty cycle of 100%. The converter utilizes current mode control and synchronous rectification for high efficiency. It also includes features such as adjustable current limit, enable, soft-start, and adjustable UVLO.

 

Packaged in a 32-VQFN (5x5mm) with an exposed pad, the TPS65263RHBT is designed for surface mount applications. The operating temperature range is -40°C to 85°C (TA). The device offers I2C read-back capabilities for power-good status, overcurrent warnings, and die temperature warnings, along with an I2C compatible interface supporting standard (100 kHz) and fast (400 kHz) modes.
