3 Description

The TPS562202 is a simple, easy-to-use, 2-A synchronous buck converter in a SOT563 package.

The device is optimized to operate with minimum external components and also optimized to achieve low standby current.

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 components. no external compensation

The TPS562202 operates in ECO mode, which maintains high efficiency during light load operation. The TPS562202 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.
