■PIN CONFIGURATION
The NJU7600 is a low voltage operation high-speed switching
regulator control IC for PWM control step-up and fly-back converter.
It incorporates a totem pole driver output, which can directly driv
an external MOS-FET easily. The NJU7600 also has a soft-star
function, dead time control and timer latch for short circuit protection
and their times are all adjustable with external parts. It is available in
8-lead DMP, MSOP (TVSP) packages and 10-lead MSOP (TVSP
package. It is suitable for battery powered applications.
