Description for the TPS563249

The TPS563249 is a simple, easy-to-use, 3 A synchronous step-down converter in SOT-23package.

The device is 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.

TPS563249 operates in Forced Continuous Conduction Mode (FCCM), which maintains fixed 1.4MHz switching frequency during light load operation and eliminates system interference. TheTPS563249 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.
