The UC2842NG4 is a current-mode PWM controller optimized for off-line and DC-to-DC converter applications. It operates within a temperature range of -40¬8C to 85¬8C and features a low start-up current of less than 1mA. The device supports a maximum duty cycle of 97% and can operate at switching frequencies of up to 500kHz. It includes essential features such as automatic feedforward compensation, pulse-by-pulse current limiting, and undervoltage lockout with hysteresis. The UC2842NG4 is packaged in an 8-DIP format, making it suitable for through-hole mounting. It is designed for applications requiring reliable performance in power supply circuits, including boost, flyback, and forward topologies.
