NJU7678
Internal 60V, 3A MOSFET Step-Up / Flyback Switching Regulator IC
GENERAL DESCRIPTION
NJU7678 is Step-up/Fly back type switching regulator IC with
PWM control. Internal soft-start function, dead time control and
timer latch function are included, requiring no external components.
All parameters can be optimized by additional external
components for design flexibility.
