Overview

UC3842A, UC3843A, UC2842A, UC2843A High Performance Current Mode Controllers The UC3842A, UC3843A series of high performance fixed frequency current mode controllers 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.

Key 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 plastic package as well as the 14.
  • pin plastic surface mount (SOIC.
  • 14). The SOIC.
  • 14 package has separate power and ground pins for the totem pole output stage. The UCX842A has UYLO thresholds of 16 V (on).
