Product details

Description

Pin No 1 2 3 4 5 6 Pin Name LATCH FB CS GND DRV VCC Function LatchïOff Input Feedback + Shutdown pin Current Sense ï Drive output VCC input Pin Description Pull the pin up or down to latchïoff the controller.

Features

a timerïbased fault detection that ensures the detection of overload and an adjustable compensation to help keep the maximum power independent of the input voltage. Due to frequency foldback, the controller exhibits excellent efficiency in light load condition while still achieving very low standby power consumption. Internal frequency jittering, ramp compensation, and a versatile latch input make this controller an excellent candidate for the robust power supply designs. A dedicated Off mode al.
