Texas Instruments TPS564208

Description

The TPS564208 is a simple, easy-to-use, 4-Asynchronous step-down converter in SOT-23package.The device is optimized to operate with minimumexternal component count and also optimized toachieve low standby current.These switch mode power supply (SMPS) devicesemploy D-CAP2 mode control providing a fasttransient response and supporting both lowequivalent series resistance (ESR) output capacitorssuch as specialty polymer and ultra-low ESR ceramiccapacitors with no external compensationcomponents.TPS564208 is available in a 6-pin 1.6-mm × 2.9-mmSOT (DDC) package, and specified from a –40°C to125°C junction temperature.
