CompareUC3845B SMD CURRENT MODE PWM IC SOT-8
Description
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, high gain error amplifier, current sensing
comparator and a high current totem pole output for driving a Power MOSFET. The UC3842 and
UC3844 have UVLO thresholds of 16V (on) and 10V (off). The UC3843 and UC3845 are 8.5V(on)
and 7.9V (off). The UC3842 and UC3843 can operate within 100% duty cycle. The UC3844 and
UC3845 can operate with 50% duty cycle.
