4.5V to 17V Input, 4A Output, Synchronous Step-Down Converter - TPS564208

TPS564208 (ACTIVE)

4.5V to 17V Input, 4A Output, Synchronous Step-Down Converter

 

Description

The TPS564208 is a simple, easy-to-use, 4-A synchronous step-down converter in SOT-23 package.

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

These switch mode power supply (SMPS) devices employ 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 no external compensation components.

The TPS564208 is available in a 6-pin 1.6-mm × 2.9-mm SOT (DDC) package, and specified from a –40°C to 125°C junction temperature.
