The peak transient output current can be 3.
5 A.
The devices are optimized to operate with minimum external component counts and also optimized to achieve low standby current.
This switching regulator employs 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.
TPS563240 operates in pulse skip mode, which maintains high efficiency during light load operation.
The TPS563240 maintain Fsw over 25-kHz under light load condition.
The TPS563240 is available in a 6-pin 1.
6-mm × 2.
9-mm SOT (DDC) package, and specified from a –40°C to 125°C junction temperature.
