Differences between members of this family are the under-voltagelockout thresholds and maximum duty TheUC384xB family ofcontrolICs providesthe nec- cycle 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 wwwwit.DhataSheet4Us.cuomitedoff-lineapplicationsThecorrespondingthresh- a minimal external parts count.
