DATA Semiconductor Components Industries, LLC, 2013 August, 2021 Rev. 181 Publication Order Number: UC3842B /DHigh PerformanceCurrent Mode ControllersUC3842B, UC3843B,UC2842B, UC2843 BThe UC3842B , UC3843B series are high Performance fixedfrequency Current mode Controllers . They are specifically designed forOff Line and DC DC converter applications offering the designera cost effective solution with minimal external components. Theseintegrated circuits feature a trimmed oscillator for precise duty cyclecontrol, a temperature compensated reference, high gain erroramplifier, Current sensing comparator, and a high Current totem poleoutput ideally suited for driving a power included are protective features consisting of input andreference undervoltage lockouts each with hysteresis, cycle by cyclecurrent limiting, programmable outpu
