Overview
®
UC2842B/3B/4B/5B UC3842B/3B/4B/5B
HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER
comparatorwhich 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 www.
