UC3842B, UC3843B series are high performance fixed frequency current mode controllers. These devices are specifically designed for off-line and DC-DC converter applications, offering designers a cost-effective solution with minimal external components. These ICs feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, a high gain error amplifier, a current sense comparator, and a high current totem pole output suitable for driving power MOSFETs. Protection features are also included, including input and reference undervoltage lockouts all with hysteresis, cycle-by-cycle current limit, programmable output dead time, and latching for single-pulse metering. These devices are available in 8-pin dual inline plug-in and surface mount (SO-8) plastic encapsulation and 14-pin plastic surface mount (SO-14) encapsulation. The SO-14 encapsulation has separate power and ground pins for the totem pole output stage. The UCX842B has UVLO thresholds of 16 V (on) and 10 V (off), suitable for offline converters. The UCX843B is tailored for low voltage thresholds with UVLO thresholds of 8.5 V (on) and 7.6 V (off).
