UC3842/3/4/5 Provides Low-Cost Current-Mode Control

In addition, the UC3842 series is optimized for ef-ficient power sequencing of off-line converters, DC to DC regulators and for driving power MOSFETs or transistors. ... flyback and boost converters operating with inductor cur-rent. The feedback components add a pole to the loop.
