The UC3842BNG from ON Semiconductor is a current-mode PWM switching controller specifically designed for low power off-line switching power supply applications. This controller offers fixed frequency operation at 52kHz with a modulation frequency of up to 65kHz and a 96% duty cycle maximum. It has a 1A maximum peak output current and a voltage regulator with voltage feedback and current limit. It also includes an external soft start ramp, under-voltage lockout, and an output on/off logic signal. The pinout is standard 8-pin DIP, SOIC, CERPACK, and flatpack packages. This device is ideal for off-line converters with low standby power requirements.
