open-in-new Find other Buck converters (integrated switch)


The TPS563207 is a simple, easy-to-use, 3-A synchronous buck converter in a SOT563 package.

The device is optimized to operate with minimum external components.

This switch mode power supply (SMPS) device employs D-CAP2™ mode control, providing a fast transient response and supporting both low-equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components.

The TPS563207 operates in FCCM mode, which maintains small ripple even at light loads. The TPS563207 is available in a 6-pin 1.6-mm × 1.6-mm SOT563 (DRL) package, and specified from a –40°C to 125°C junction temperature.
