NCP1377, NCP1377B  
PWM Current−Mode  
Controller for Free−Running  
Quasi−Resonant Operation  
The NCP1377 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). Due  
to its inherent skip cycle capability, the controller enters burst mode  
as soon as the power demand falls below a predetermined level. As  
this happens at low peak current, no audible noise can be heard. For  
NCP1377, an internal 8.0 ms timer prevents the free−run frequency to  
exceed 100 kHz (therefore below the 150 kHz CISPR−22 EMI  
starting limit), while the skip adjustment capability lets the user  
select the frequency at which the burst foldback takes place. For  
NC1377B, the internal timer duration is reduced to 3.0 ms to allow  
operation at higher frequencies (up to 300 kHz).

The transformer core reset detection is done through an auxiliary  
winding which, brought via a dedicated pin, also enables fast  
Over Voltage Protection (OVP). Once an OVP has been detected, the  
IC permanently latches off. The 1377 features a sampling time of  
4.5 ms whereas it is 1.5 ms for the B version.

The NCP1377 also features an efficient protective circuitries  
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. Finally an internal 1.0 ms  
Soft−Start eliminates the traditional startup stress.
