Description

The MC34067DWG/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. MC34067DWG 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
