Datasheet Summary

® UC2842B/3B/4B/5B UC3842B/3B/4B/5B HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER paratorwhich alsoprovidescurrent limit control, and a totem pole output stage designed to source or sink high peakcurrent. The outputstage, suitable for driving N-Channel MOSFETs, is low in the offstate. Differences between members of this family are the DESCRIPTION under-voltagelockout thresholds and maximum duty TheUC384xB family ofcontrolICs providesthe neccycle ranges. The UC3842B and UC3844B have essary Features to implement off-line or DC to DC UVLO thresholds of 16V (on) and 10V (off), ideally fixed frequency current mode control schemes .. with suitedoff-lineapplicationsThecorrespo...
