The Texas Instruments TPS65263RHBR is a versatile triple synchronous step-down (buck) converter designed for power management applications. It supports an input voltage range of 4.5V to 18V and provides three output channels with current capabilities of 3A, 2A, and 2A respectively. A key feature is its I2C-controlled Dynamic Voltage Scaling (DVS), allowing for programmable output voltages from 0.68V to 1.95V with fine 10mV steps, enabling power optimization.
This converter operates at a fixed 600kHz switching frequency, incorporating synchronous rectification for improved efficiency. It offers features such as adjustable current limit, enable control, soft-start, and power good indication for each output. The device is housed in a 32-VQFN (5x5mm) package, suitable for surface mounting.
Designed for a wide operating temperature range of -40°C to 85°C, the TPS65263RHBR is well-suited for various electronic systems requiring efficient and flexible DC/DC conversion. Its I2C interface allows for read-back of power-good status, overcurrent warnings, and die temperature warnings, facilitating system monitoring and control.
