Fonctionnalités et applications

The MC34067 is a High Performance Resonant Mode Controllers.

The MC34067/MC33067 are high performance zero voltage switch resonant mode controllers designed for off−line and dc−to−dc converter applications that utilize frequency modulated constant off−time or constant deadtime control. These integrated circuits feature a variable frequency oscillator, a precise retriggerable one−shot timer, temperature compensated reference, high gain wide bandwidth error amplifier, steering flip−flop, and dual high current totem pole outputs ideally suited for driving power MOSFETs. Also included are protective features consisting of a high speed fault comparator and latch, programmable soft−start circuitry, input undervoltage lockout with selectable thresholds, and reference undervoltage lockout. These devices are available in dual−in−line and surface mount packages.

Key Features:

  • Zero Voltage Switch Resonant Mode Operation
  • Variable Frequency Oscillator with a Control Range Exceeding 1000:1
  • Precision One−Shot Timer for Controlled Off−Time
  • Internally Trimmed Bandgap Reference
  • 4.0 MHz Error Amplifier
  • Dual High Current Totem Pole Outputs
  • Selectable Undervoltage Lockout Thresholds with Hysteresis
  • Enable Input
  • Programmable Soft−Start Circuitry
  • Low Startup Current for Off−Line Operation
  • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant
