The fundamentalchallenge of power supply design is to simultaneously realize two conflicting objectives: good electrical performanceand low cost. The
UC3842 is an integrated pulse width modulator (PWM) designedwith both theseobjectives inmind.This IC provides designersan inexpensive controller
with which they can obtain all the performance advantages of current-mode operation. In addition,theUC3842 is optimized for efficient power sequencing
of off-line converters and for driving increasingly popularPOWERMOS.
