The UC3844AD is a current mode PWM controller designed for off-line and DC-DC converters. It operates with a maximum voltage of 30V and a current limit of 1A, at frequencies up to 500kHz. The device includes undervoltage lockout (UVLO) with 16V/10V thresholds and a maximum duty cycle of 50%.
This controller features low start-up current (< 0.5mA), trimmed oscillator discharge current, automatic feedforward compensation, and pulse-by-pulse current limiting. It offers enhanced load response characteristics and double pulse suppression. The UC3844AD is housed in a 14-pin SOIC package and operates within a temperature range of 0°C to 70°C.
This part is not recommended for new designs. Consider alternatives like the TL2844BDR.
