  • FAIRCHILD AN-6756 Applying FAN6756 to Control a Flyback Power Supply with Ultra-Low Standby Power handbook

    FAN6756 is a new green-mode PWM controller from Fairchild Semiconductor Corporation. It incorporates innovative mWSaver™ technology, which dramatically reduces the standby and no-load power consumption of a power supply with minimum external components. This application note presents the step-by-step design with an example of applying FAN6756 to a flyback power supply. It covers designing of the transformer and selecting the external components.

  • FAIRCHILD AN-6083 Highly Integrated Dual-PWM Combination Controller handbook

    This application note introduces the features of FAN6791 and shows how to design a high-performance power supply.

  • FAIRCHILD AN-6741 Flyback Power Supply Control with the SG6741 handbook

    This application note describes a design strategy for a high- efficiency, compact flyback converter. Design considerations, mathematical equations, and guidelines for a printed circuit board layout are presented.

  • FAIRCHILD SG6742 - Highly Integrated Green-Mode PWM Controller handbook

    This application note describes a detailed design strategy for a high-efficiency, compact flyback converter. Design considerations, mathematical equations, and guidelines for a Printed-Circuit-Board (PCB) layout are presented.

  • FAIRCHILD Applying SG6902 to Control a CCM PFC Flyback/PWM Power Supply handbook

    SG6902 is a controller designed for power supplies that consist of boost PFC and flyback PWM. It requires few external components to achieve green-mode operation and versatile protections and compensations. The proprietary interleave switching synchronizes the PFC and PWM stages and reduces switching noise. At light loads, PFC stage is turned off to save power and the PWM switching frequency increases.
