The UC3842DTR is a Current-Mode PWM Controller from Texas Instruments, designed for use in off-line and DC-to-DC converters. It operates within a temperature range of 0°C to 70°C and features a low start-up current of less than 1mA. The controller includes automatic feedforward compensation, pulse-by-pulse current limiting, and enhanced load-response characteristics. It also has an undervoltage lockout with hysteresis and double-pulse suppression, making it suitable for various applications, including switching regulators and transformer-coupled DC-DC converters. The device supports operation frequencies of up to 500kHz and is available in a 14-pin SOIC package.
