TPS565208 (ACTIVE)

4.5V to 17V, 5A Synchronous Step-Down Voltage Regulator in SOT23

 

Description

The TPS565208 is a simple, easy-to-use, 5-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.

This switch mode power supply (SMPS) device employs D-CAP2™ mode control, which provides fast transient response and requires no external compensation components. D-CAP2™ also allows the 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°C to 125°C junction temperature range.
