Texas Instruments  TPS565201DDCR

The TPS565201 is a simple, easy-to-use, 5-A synchronous step-down converter.

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

This switch mode power supply (SMPS) device employs D-CAP2™ control, which provides fast transient response and requires noexternal compensation components. D-CAP2 also allows the use of low-equivalent series resistance(ESR) specialty polymer capacitors and ceramic output capacitors.

The TPS565201 operates in pulse skip mode, maintaining high efficiency during light loadoperation.

The TPS565201 device is available in a 6-pin 1.6-mm × 2.9-mm SOT (DDC) package, andoperates over a –40°C to 125°C junction temperature range.
