UC2842BD [Onsemi]

The UC3842B, UC3843B series are high performance fixed frequency current mode controllers specifically designed for off-line and DC-DC converter applications, offering a cost-effective solution with minimal external components. They 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 for driving power MOSFETs. Protective features include input and reference undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, programmable output deadtime, and a latch for single pulse metering.
