UC3843 IC – Current-Mode PWM Controller IC
The UC3842/UC3843/UC3844/UC3845 are fixed frequency current-mode PWM controller. They are specially designed for Off-Line and DC to DC converter applications with minimum external components. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, a high gain error amplifier, current sensing comparator, and a high current totem pole output for driving a Power MOSFET.
