TPS65276VRHHR Description

Short technical summary and product information.

The Texas Instruments TPS65276VRHHR is a dual synchronous step-down DC/DC switching regulator designed for power management applications. It features a wide input voltage range of 4.5-V to 18-V, making it suitable for various power sources.

 

This converter offers two output channels, with Buck 1 capable of delivering up to 6A and Buck 2 up to 3.5A. The output voltage is programmable from 0.68V to 1.95V in 10mV steps via a 7-bit VID setting through an I2C interface. The device supports standard (100 kHz) and fast (400 kHz) I2C modes.

 

Key features include adjustable switching frequency from 200 kHz to 1.6 MHz, slew rate control for output voltage transitions, and pulse skipping mode for high efficiency at light loads. It also incorporates cycle-by-cycle overcurrent protection and over-temperature protection. The TPS65276VRHHR is available in a 36-VQFN exposed pad package, suitable for surface mounting.

 

Designed for efficient power conversion, this regulator is ideal for applications requiring flexible and reliable voltage regulation. Its integrated features simplify design and reduce component count.
