circuits for the implementation of leading edge, average current, and
"boost"-type power factor correction; the FAN9673 enables the design of a
power supply that fully complies with the IEC1000-3-2 specification.
Integration of these devices provides cost-effective design and reduces external components.
Operates two parallel-connected boost power trains 180º out of phase.
Designed for power supplies that consist of boost PFC and PWM and
require very few external components to achieve protection/compensation.
