Description

The TPS563231 is simple, easy-to-use, 3 A synchronous step-down converters in SOT563 package.The devices are 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, TPS563231 operates in pulse skip mode (PSM), which maintains high efficiency. The TPS563231 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.
