TPS65279RHHR Description

Short technical summary and product information.

The Texas Instruments TPS65279RHHR is a monolithic dual synchronous buck converter designed for a wide input voltage range of 4.5V to 18V. This device offers up to 5A of continuous output current per buck, and the two bucks can be paralleled to deliver up to 10A. It operates with a constant frequency peak current mode control, simplifying compensation and providing fast transient response.

 

The converter supports an adjustable switching frequency from 200 kHz to 1.6 MHz, set by an external resistor. It includes dedicated enable and soft-start pins for each buck, offering flexibility in power-up sequencing. Pulse skipping mode is available to achieve high efficiency at light loads. The TPS65279RHHR also features cycle-by-cycle overcurrent protection and over-temperature protection.

 

This component is available in a 36-pin VQFN (6x6 mm) package with an exposed pad for enhanced thermal performance. The mounting type is surface mount, making it suitable for various PCB designs. Its operating temperature range is -40°C to 125°C (TJ).
