TPS65279VRHHR Description

Short technical summary and product information.

The Texas Instruments TPS65279VRHHR is a dual, 5A synchronous step-down DC DC switching regulator designed for power management applications. It features a wide input voltage range from 4.5V to 18V and supports an output voltage range from 0.68V to 15V, which can be programmed via I2C or a resistor divider.

 

This device operates with a switching frequency adjustable from 200 kHz to 1.6 MHz, utilizing peak current-mode control. It includes features such as light-load efficiency, phase interleaving, and soft-start for each buck. The TPS65279VRHHR is available in a 36-VQFN (6x6 mm) package, suitable for surface mounting.

 

Key electrical characteristics include a maximum output current of 5A per channel, with the option to parallel both channels for up to 10A. The operating temperature range is -40°C to 85°C. The regulator also provides an I2C compatible interface for control and monitoring, including read-back of power good status and die temperature warnings.
