Text: DN-89 Design Note Comparing the UC3842 , UCC3802, and UCC3809 Primary Side PWM Controllers by Lisa Dinwoodie Introduction Despite the fact that the UC3842 and the UCC3802 are pin for pin , user transition from either the UC3842 or the UCC3802 to the UCC3809 in an existing design. Figures , . Soft-Start and Shutdown The UC3842 requires an external PNP, resistor, and capacitor in order to have full , pin low as in the UC3842 and the UCC3802. Bias The BiCMOS design of the UCC3802 and the UCC3809
