Overview
NJU7606 Step-Up / Flyback Switching Regulator IC with Load Switch Function ■GENERAL DESCRIPTION The NJU7606 are low voltage operation high speed switching regulator control ICs for step-up and flyback converter, with a load switch function.
The load switch function can disrupt the current flow to the load in standby mode and latch mode.
The NJU7606 also have a soft-start function, dead time control and timer latch for short circuit protection and their times are all adjustable with external parts.
The NJU7606 is available in 10-lead MSOP (TVSP) package.
They are suitable for battery powered applications.
