Texas Instruments TPS565208

Description

The TPS565208 is a simple, easy-to-use, 5-Asynchronous step-down converter in SOT-23package.The device is optimized to operate with minimumexternal component count and also optimized toachieve low standby current.This switch mode power supply (SMPS) deviceemploys D-CAP2™ mode control, which provides fasttransient response and requires no externalcompensation components. D-CAP2™ also allowsthe use of low-equivalent series resistance (ESR)specialty polymer capacitors and ceramic capacitors.The TPS565208 is available in a 6-pin 1.6-mm × 2.9-mm SOT (DDC) package, and operates over a –40°Cto 125°C junction temperature range.
