General description
The 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 MOSFET.Also included are protective features consisting of input andreference undervoltage lockouts each with hysteresis, cycle−by−cyclecurrent limiting, programmable output deadtime, and a latch for singlepulse metering.These devices are available in an 8−pin dual−in−line and surfacemount (SOIC−8) plastic package as well as the 14−pin plastic surfacemount (SOIC−14). The SOIC−14 package has separate power andground pins for the totem pole output stage.The UCX842B has UVLO thresholds of 16 V (on) and 10 V (off),ideally suited for off−line converters. The UCX843B is tailored forlower voltage applications having UVLO thresholds of 8.5 V (on) and7.6 V (off).
