Product Overview

The UC2842BNG is a high-performance fixed frequency current-mode Pulse Width Modulation (PWM) Controller specifically designed for off-line and DC to DC converter applications offering the designer a cost-effective solution with minimal external components. This integrated circuit features 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.
  • Trimmed oscillator for precise frequency control
  • Automatic feed forward compensation
  • Internally trimmed reference with undervoltage lockout
  • High current totem pole output
  • Undervoltage lockout with hysteresis
  • Low startup and operating current
