NCP1249AD65GEVB: 65 W Adapter<10 MW No Load Standby Evaluation Board

The NCP1249 is a highly integrated high−voltage PWM controller capable of delivering a rugged and high performance offline power supply with extremely low no−load consumption. With a supply range up to 30 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.
