NCP1254 Datasheet (ON Semiconductor) - Current-Mode PWM Controller

NCP1254, Current-Mode PWM Controller

NCP1254 Product Preview Current-Mode PWM Controller for Off-line Power Supplies featuring Peak Power Excursion The NCP1254 is a highly integrated PWM controller capable of delivering a rugged and high performance offline power supply in a TSOP 6 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 i
