1 / 11 page © Semiconductor Components Industries, LLC, 2006 July, 2006 − Rev. 3 1 Publication Order Number: MC34066/D MC34066, MC33066 High Performance Resonant Mode Controllers The MC34066/MC33066 are high performance resonant mode controllers designed for off−line and dc−to−dc converter applications that utilize frequency modulated constant on−time or constant off−time control. These integrated circuits feature a variable frequency oscillator with programmable deadtime, precision retriggerable one−shot timer, temperature compensated reference, high gain wide−bandwidth error amplifier with a precision output clamp, 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. • Variable Frequency Oscillator with a Control Range Exceeding 1000:1 • Programmable Oscillator Deadtime Allows Constant Off−Time Operation • Precision Retriggerable One−Shot Timer • Internally Trimmed Bandgap Reference • 5.0 MHz Error Amplifier with Precision Output Clamp • 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 Figure 1.
