Texas Instruments TPS562203

Beschreibung

TPS562203, TPS562206 are simple, easy-to-use, 2A synchronous buck converters in a SOT563 package.The devices are designed to operate with minimum external component counts and also designed to achieve low standby current.This switch mode power supply (SMPS) device employs D-CAP3 control mode, 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.
