TPS65273VRHHR Description

Short technical summary and product information.

The Texas Instruments TPS65273VRHHR is a versatile dual synchronous step-down converter designed for efficient power management. It supports an input voltage range of 4.5V to 18V and can deliver up to 3.5A of continuous output current per channel. The device features an I2C interface for 7-bit VID programmable output voltage, ranging from 0.68V to 1.95V in 10mV steps, offering flexibility in power delivery.

 

Key electrical characteristics include a programmable switching frequency from 200kHz to 1.6MHz, enabling optimization for efficiency and noise performance. The TPS65273VRHHR incorporates features like phase interleaving, soft-start, synchronous rectification, and pulse skipping mode for high light-load efficiency. It operates within an ambient temperature range of -40°C to 85°C.

 

Packaged in a 36-VQFN (6x6mm) or 36-VFQFN exposed pad, this component is designed for surface mount applications. Its dual-channel capability and paralleling option for higher current output make it suitable for various power supply designs requiring compact and efficient voltage regulation.
