ML4813 Datasheet (Micro Linear) - Flyback Power Factor Controller

ML4813, Flyback Power Factor Controller

The ML4813 is a PWM controller designed for use in a discontinuous "flyback" or "buck-boost" type power factor correction (PFC) system for low power, low cost applications.

The circuit includes a precision reference, oscillator, error amplifier, over-voltage comparator, over-current comparator, and
