NCP1254 - Current-Mode PWM Controller for Off-line Power Supplies featuring Peak Power Excursion
ON Semiconductor
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 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 setpoint.
