Overview

The MC34023 series are high speed, fixed frequency, single-ended pulse width modulator controllers optimized for high frequency operation. 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 an oscillator, a temperature compensated reference, a wide bandwidth error amplifier, a high speed 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, and a latch for single pulse metering.

The flexibility of this series allows it to be easily configured for either current mode or voltage mode control.

  • 50 ns Propagation Delay to Output
  • High Current Totem Pole Output
  • Wide Bandwidth Error Amplifier
  • Fully-Latched Logic with Double Pulse Suppression
  • Latching PWM for Cycle-By-Cycle Current Limiting
  • Soft-Start Control with Latched Overcurrent Reset
  • Input Undervoltage Lockout with Hysteresis
  • Low Start-Up Current (500 µA Typ)
  • Internally Trimmed Reference with Undervoltage Lockout
  • 90% Maximum Duty Cycle (Externally Adjustable)
  • Precision Trimmed Oscillator
  • Voltage or Current Mode Operation to 1.0 MHz
  • Functionally Similar to the UC3823
  • Pb-Free Packages are Available
