The UC3844ADTR from Texas Instruments is a current mode PWM controller suitable for various off-line and DC-DC converter topologies including Boost, Buck, Flyback, and Forward. It features a wide operating voltage range of 10V to 30V and can operate at frequencies up to 500kHz with a maximum duty cycle of 48%.
Key electrical features include low start-up current (<0.5mA), pulse-by-pulse current limiting, automatic feedforward compensation, and double pulse suppression. The device also incorporates undervoltage lockout with hysteresis (16V/10V) and a high-current totem pole output.
This controller is available in a 14-SOIC package designed for surface mounting. Its operating temperature range is 0°C to 70°C (TA). The UC3844ADTR is optimized for efficient power management in a variety of electronic designs.
This part is pin-for-pin compatible with the UCx84x family, offering improved features such as a trimmed oscillator discharge current of 8.3mA and enhanced load response characteristics.
