1.8V Operate PWM control Step-Up / Flyback switching regulator IC
■GENERAL DESCRIPTION
NJU7677 is a high speed low voltage operation switching
regulator control IC. It features a totem pole driver that can directly
drive an external MOS-FET.
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.
