The NCP1337 combines a true current mode modulator and a
demagnetization detector which ensures full Borderline/Critical
Conduction Mode in any load/line conditions together with
minimum drain voltage switching (Quasi ? Resonant operation). The
transformer core reset detection is done internally, without using any
external signal, due to the Soxyless concept. The frequency is
internally limited to 130 kHz, preventing the controller to operate
above the 150 kHz CISPR ? 22 EMI starting limit.
By monitoring the feedback pin activity, the controller enters skip
mode as soon as the power demand falls below a predetermined
level. As each restart is softened by an internal Soft ? Skip t , and as
the frequency cannot go below 25 kHz, no audible noise can be
heard.
The NCP1337 also features an efficient protective circuitry which,
in presence of an overcurrent condition, disables the output pulses
and enters a safe burst mode, trying to restart. Once the default has
gone, the device auto ? recovers. Also included is a bulk voltage
monitoring function (known as brown ? out protection), an adjustable
overpower compensation, and a V CC OVP. The controller
immediately restarts after any of these conditions, unless the fault
timer has timed out. Finally, an internal 4.0 ms soft ? start eliminates
the traditional startup stress.
