The document is a technical data sheet for the MC34067/MC33067 high performance zero voltage switch resonant mode controllers.
These controllers are designed for off-line and dc-to-dc converter applications and 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.
The document includes information on the pin connections, ordering information, package details, maximum ratings, electrical characteristics, and simplified block diagram.
It also provides graphs and figures illustrating the performance characteristics of the controllers.
