Overview

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, inputundervoltage lockout with selectable thresholds, and reference undervoltage lockout.

These devices are available in dual-in-line and surface mount packages.

  • 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
  • Pb-Free Packages are Available*

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
