NJW4140 Switching Regulator ICs

Nisshinbo NJW4140 Switching Regulator ICs for Boost / Flyback converter are integrated with a built-in highly effective N-channel MOSFET driving circuit. This built-in pulse-by-pulse current detecting type over-current protection limits the output current at over-load. The automotive NJW4140 switching regulator ICs feature wide input voltage ranging from 3V to 40V and wide oscillating frequency ranging from 40kHz to 1MHz. These Nisshinbo ICs are ideally used in automotive electronic control units (ECU) and industrial control equipment.
