Description

General part information

TPS56221 Series

The TPS56221 device is a high-efficiency and high-current synchronous buck converter designed to operate from a supply from 4.5 V to 14 V. The device can produce an output voltage as low as 0.6 V at loads up to 25 A. Integrated NexFET™ Power MOSFETs provide a small footprint and ease of use.

The device implements a voltage-mode control with voltage feed-forward compensation that responds instantly to input voltage change.

The TPS56221 is available in a thermally enhanced 22-pin PQFN (DQP) PowerPAD package.
