NJU7677  
1.8V Operate PWM control Step-Up / Flyback switching regulator IC  
GENERAL DESCRIPTION  
PACKAGE OUTLINE  
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.
