NCP1256  
Low Power Offline PWM  
Current Mode Controller  
with Brown-Out Protection  
The NCP1256 includes everything to build cost−effective switch  
mode power supplies ranging from a few watts up to several tens of  
watts. Housed in a tiny TSOP−6 package, the part can be supplied up  
to 30 V. It hosts a jittered 65 or 100−kHz switching circuitry operated  
in peak current mode control. When the power in the secondary side  
starts decreasing, the controller automatically folds back its switching  
frequency down to a minimum level of 26 kHz. As the power further  
goes down, the part enters skip cycle while freezing the peak current.  
NCP1256 comes with several protection features such as a  
timer−based auto−recovery short circuit protection, lossless OPP, and  
an easily adjustable Brown Out (BO) pin. Two inputs are provided to  
latch off the part in a practical way, for instance with OVP and OTP  
events. Several options exists to chose latch or auto−recovery for these  
events.
