PR9853 - Low Cost Green-Power PWM Controller
PR9853 is a highly integrated and low cost current mode PWM controller, which is ideal for low power current mode of offline AC-DC fly-back converter applications.
By adjusting the external resistors to change the operating frequency, and then IC automatically enters PFM or hiccup mode in light-load
