●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.
