Overview
The TPS565208DDCR is a 5-A synchronous step-down converter produced by Texas Instruments. This device is designed to operate with a minimum external component count and is optimized for low standby current. It features the proprietary D-CAP2™ mode control, which provides fast transient response and supports the use of low-equivalent series resistance (ESR) specialty polymer capacitors and ceramic capacitors. The TPS565208 is available in a 6-pin SOT-23 package and operates over a junction temperature range of –40°C to 125°C.
