The TPS563201 and TPS563208 are simple, easy-to-use, 3A synchronous step-down converters in SOT-23 package.

The devices are designed to operate with minimum external component counts and also designed to achieve low standby current.

These switch mode power supply (SMPS) devices employ D-CAP2 control scheme 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.

The TPS563201 operates in pulse skip mode, which maintains high efficiency during light load operation. The TPS563201 and TPS563208 are available in a 6-pin 1.6mm × 2.9mm SOT (DDC) package, and specified from a –40°C to 125°C junction temperature.
