NCP1255, Current-Mode PWM Controller

NCP1255 Current-Mode PWM Controller for Off-line Power Supplies featuring Peak Power Excursion The NCP1255 is a highly integrated PWM controller capable of delivering a rugged and high performance offline power supply in a SOIC 8 package.

With a supply range up to 35 V, the controller hosts a jittered 65 kHz switching circuitry operated in peak current mode control.

When the power on the secondary side starts to decrease, the controller automatically folds back its switching fre
