High Performance

Current Mode Controllers

The UC3842B, UC3843B series are high performance fixed frequency current mode controllers. They are specifically designed for Off±Line and dc±to±dc converter applications offering the designer a cost±effective solution with minimal external components. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, current sensing comparator, and a high current totem pole output ideally suited for driving a power MOSFET.

Also included are protective features consisting of input and reference undervoltage lockouts each with hysteresis, cycle±by±cycle current limiting, programmable output deadtime, and a latch for single pulse metering.

These devices are available in an 8±pin dual±in±line and surface mount (SO±8) plastic package as well as the 14±pin plastic surface mount (SO±14). The SO±14 package 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), ideally suited for off±line converters. The UCX843B is tailored for lower voltage applications having UVLO thresholds of 8.5 V (on) and 7.6 V (off).
