UC3843 Fixed Frequency Current Mode PWM Controller DESCRIPTION UC3843 is a fixed frequency current-mode PWM controller. It is specially designed for Off Line and DC-to-DC converter applications with minimal external ponent. This integrated circuit Features a trimmed oscillator for precise duty cycle control, a temperature pensated reference, a high gain error amplifier, a current sensing parator, and a high current totem pole output ideally suited for driving a power MOSFET. The device is protective Features consisting of input and reference under-voltage lockouts each with hysteresis, cycle-by-cycle current limiting.
