Description

The NJM2379 is a high speed switching regulator control IC，and directly drive an external power MOS-FET to use internal totempole output circuit. The NJM2379 operate slave mode which synchronous external oscillation frequency，and the slave mode reduce the total noise. The NJM2379 is suitable for flyback type switching regulation up to 10W and several output power supply for LCD panel.
