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, 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.

• 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
