Texas Instruments  TPS562231DRLR

The TPS562231is a simple, easy-to-use, 2-A synchronous step-down converter in SOT563 package.

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

These switch mode power supply (SMPS) devices employ D-CAP3 mode control providing a fasttransient response and supporting both low-equivalent series resistance (ESR) output capacitorssuch as specialty polymer and ultra-low ESR ceramic capacitors with no external compensationcomponents.

During light load operation, TPS562231 operates in pulse skip mode (PSM), which maintainshigh efficiency. The TPS562231 is available in a 6-pin 1.6-mm × 1.6-mm SOT563 (DRL) package, andspecified from a –40°C to 125°C junction temperature.
