NJU7631 Step-Down Switching Regulator IC with Power Saving PWM/PFM control ■ GENERAL DESCRIPTION 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. ■ PACKAGE OUTLINE NJU7631RB1 (MSOP8 (TVSP8)) ■ FEATURES ■ PRODUCT VARIATION ● Automatic PWM/PFM Control ● Operating Voltage 2.
