The TPS563240DDCR is a simple, easy-to-use, 3-A synchronous step-down regulator in SOT-23package. The peak transient output current can be 3.5 A.
The devices are optimized to operate with minimum external component counts and alsooptimized to achieve low standby current.
This switching regulator employs D-CAP3 mode control providing a fast transient responseand supporting both low-equivalent series resistance (ESR) output capacitors such as specialtypolymer and ultra-low ESR ceramic capacitors with no external compensation components.
TPS563240DDCR operates in pulse skip mode, which maintains high efficiency during light loadoperation.The TPS563240DDCR maintain Fsw over 25-kHz under light load condition. TheTPS563240DDCR is available in a 6-pin 1.6-mm × 2.9-mm SOT (DDC) package, and specified from a –40°C to125°C junction temperature.
