Product Overview

The UC3843BD1G is a high performance fixed frequency Current Mode Controller specifically designed for OFF-line and DC-DC converter applications. This integrated circuit features a trimmed oscillator for precise duty cycle control, a temperature compensated reference and high gain error amplifier, current sensing comparator and a high current totem pole output ideally suited for driving a power MOSFET. Also includes protective features consisting of input and reference under-voltage lockouts each with hysteresis, cycle-by-cycle current limiting, programmable output dead-time and a latch for single pulse metering.
  • Trimmed oscillator for precise frequency control
  • Automatic feed forward compensation
  • Latching PWM for cycle-by-cycle current limiting
  • Internally trimmed reference with under-voltage lockout
  • High current totem pole output
  • Under-voltage lockout with hysteresis
  • Low start-up and operating current
