The uc3842 /3/4/5is an integrated pulse width modulator (PWM) designedwith both these objectives in mind. This IC PROVIDES de-signers an inexpensive controller with which they can ob-tain all the performance advantages of current mode op-eration. In addition, the uc3842 series is optimized for ef-ficient power sequencing of off-line converters, DC to DCregulators and for driving power MOSFETs or APPLICATION note PROVIDES a functional description ofthe uc3842 family and highlights the features of each in-dividual member, the uc3842 , UC3843, UC3844 andUC3845 Throughout the text, the uc3842 part numberwill be referenced, however the generalized circuits andperformance characteristics apply to each member of theUC3842 series unless otherwise noted.
