Texas Instruments TPS565201

Description

The TPS565201 is a simple, easy-to-use, 5-Asynchronous step-down converter.The device is optimized to operate with minimumexternal component counts and also optimized toachieve low standby current.This switch mode power supply (SMPS) deviceemploys D-CAP2™ control, which provides fasttransient response and requires no externalcompensation components. D-CAP2 also allows theuse of low-equivalent series resistance (ESR)specialty polymer capacitors and ceramic outputcapacitors.The TPS565201 operates in pulse skip mode,maintaining high efficiency during light load operation.The TPS565201 device is available in a 6-pin 1.6-mm× 2.9-mm SOT (DDC) package, and operates over a–40°C to 125°C junction temperature range.
