NJU7631
Step-Down Switching Regulator IC with Power Saving PWM/PFM control
■GENERAL DESCRIPTION
NJU7631 is a high speed low voltage operation switching
regulator control IC with power saving PWM/PFM control.
Automatic PWM/PFM control improves power efficiency at light
load. 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.
