NJU7610 Series
Step-Up / Flyback switching regulator IC with Over Current Protection

Download Datasheet

  • Description

    The NJU7610 is a low voltage operation high-speed switching regulator control IC for step-up and flyback converter, with a pulse-by-pulse over-current protection. The pulse-by-pulse over-current protection circuit can limit the over current in switching operation. It incorporates a totem pole output, which can drive an external MOS-FET easily. It also has a soft-start function and dead time control and their times are all adjustable with external parts.The NJU7610 is available in 8-lead DMP and MSOP (TVSP) packages.
