NJU7632
Step-Down switching regulator IC with standby function
■GENERAL DESCRIPTION
NJU7632 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. The standby function realizes
low power consumption at the time of standby.
