NCP1337

PWM Current−Mode

Controller for Free Running

Quasi−Resonant Operation

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.

MARKING

DIAGRAM

By monitoring the feedback pin activity, the controller enters

ripple mode as soon as the power demand falls below a

predetermined level. As each restart is softened by an internal

soft−start, 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 OVP. Finally, an internal 4.0 ms

soft−start eliminates the traditional startup stress.
