NCP1362 Primary Side PWM Controller

Pin Name Function 1 Vs/ZCD Connected to the auxiliary winding; this pin senses the voltage output for the primary regula- tion and detects the core reset event for the Quasi *Resonant mode of operation. 2 Comp This is the error amplifier output. The network connected between this pi.

Primary Side PWM Controller for Low Power Offline SMPS NCP1362 The NCP1362 is a highly integrated primary side quasi resonant flyback controller capable of controlling rugged and high performance off line power supplies. Due to a Novel Method this new controller saves the secondary feedback circuitry for Constant Voltage and Constant Current regulation, achieving excellent line and load regulation without traditional opto coupler and TL431 voltage reference. The NCP1362 o.
