The fundamental challenge of power supply design is tosimultaneously realize two conflicting objectives: goodelectrical performance and low cost. The UC3842/3/4/5is an integrated pulse width modulator (PWM) designedwith both these objectives in mind. This IC provides designersan inexpensive controller with which they can obtainall the performance advantages of current mode operation.In addition, the UC3842 series is optimized for efficientpower sequencing of off-line converters, DC to DCregulators and for driving power MOSFETs or transistors.
