The TPS562231 is 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 also optimized to achieve low standby current.

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

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