The UCC2894DR is a PWM controller designed for offline switcher applications, particularly suitable for active clamp/reset forward and flyback converters. It features peak current-mode control with cycle-by-cycle current limiting, ensuring reliable operation. The device includes a 110-V input startup regulator, making it capable of handling high-voltage applications. It offers a programmable soft start, accurate line undervoltage and overvoltage thresholds, and a synchronizable oscillator with a maximum frequency of 1.0 MHz. The UCC2894DR is optimized for high-efficiency, low EMI/RFI power supplies, making it ideal for applications such as server power supplies, telecom, and high-power adapters. The device operates within a temperature range of -40¬8C to 125¬8C and is available in a 16-pin SOIC package.
