The UC3844N is a fixed-frequency current-mode Pulse Width Modulation (PWM) controller designed by N-A for off-line and DC-to-DC converter applications requiring minimal external components. This integrated circuit features a trimmed oscillator for precise duty cycle control, a temperature-compensated reference, a high-gain error amplifier, a current sensing comparator, and a high-current totem pole output for driving a Power MOSFET.
Key electrical characteristics include a maximum supply voltage of 30V and an output current of ±1A. The device operates at oscillation frequencies up to 500 kHz, with a typical frequency of 500 kHz at 25°C. It includes Under Voltage Lockout (UVLO) thresholds of 16V (on) and 10V (off) for the UC3844 variant. The maximum duty cycle for the UC3844 is specified at 50%.
The UC3844N is available in 8-DIP, 8-SOP, and 14-SOP packages. Thermal data indicates power dissipation capabilities varying by package type, with the 8-DIP package rated for 1200 mW at 25°C, the 8-SOP for 460 mW, and the 14-SOP for 680 mW. The storage temperature range is -65°C to +150°C.
