NJU7631  
Step-Down Switching Regulator IC with Power Saving PWM/PFM control  
GENERAL DESCRIPTION  
PACKAGE OUTLINE  
The NJU7631 is a low voltage operation high-speed switching  
regulator control IC for step-down converter, with PWM/PFM  
switching control. It can improve a switching efficiency on light load  
with automatically changing between PWM and PFM controls. It  
incorporates a totem pole output, which can drive an external  
MOS-FET easily. The NJU7631 also has a soft-start function, dead  
time control and timer latch for short circuit protection and their  
times are all adjustable with external parts. It is available in a small  
and thin 8-lead MSOP (TVSP) package.
