Overview
The TPS565201DDCR is a 5-A synchronous step-down converter produced by Texas Instruments. This device is designed to be simple and easy to use, optimized for minimal external component counts and low standby current. It employs the proprietary D-CAP2™ mode control, which provides fast transient response and does not require external compensation components. The TPS565201DDCR operates in pulse-skip mode, maintaining high efficiency during light load operation. It is available in a 6-pin TSOT-23-6 package and operates over a junction temperature range of –40°C to 125°C.
