  • FAIRCHILD AN-6206 Manual

    This application note provides a primary-side synchronous rectification (SR) trigger solution for dual-forward converter (PFC). The solution employs the FAIRCHILD FAN6210 SR controller, which controls the FAN6206 SR driver to achieve low conduction loss SR, and to reduce the overall power loss of PFC.

  • FAIRCHILD AN-6026 Manual

    This is an application note that describes how to design a power factor correction circuit using FAN7529

  • FAIRCHILD AN4121 Manual

    This application note introduces the FAN7527B's features and characteristics, including the internal circuit structure, working principle and application circuits.

  • FAIRCHILD 9013 Manual

    This document describes how to reduce switching losses in a step-up converter using QFETs

  • FAIRCHILD AN-6027 Manual

    This application note describes a power factor correction (PFC) circuit design using the FAN7530. The circuit operates in the critical conduction mode (CRM).

  • FAIRCHILD 9015 Manual

    This application note illustrates ways in which QFET power MOSFETs may be used in switched mode power supplies. It describes a 100KHz, 180W simple off-line power supply with three regulated DC voltages.

  • FAIRCHILD AN4107 Manual

    The FAN7527 is an active power factor correction (PFC) controller for boost PFC application which operates in the critical conduction mode. It turns on MOSFET when the inductor current reaches zero and turns off MOSFET when the inductor current meets the desired input current reference voltage as shown in Fig. 1. In this way, the input current waveform follows that of the input voltage, therefore a good power factor is obtained.

  • FAIRCHILD AN4129 Manual

    This document describes the operation and features of the FAN7601. This device is a BCDMOS programmable frequency current mode PWM controller which is designed for off-line adapter applications and auxiliary power supplies. To reduce power loss at light and no load, the FAN7601 operates in burst mode and it includes a start-up switch to reduce the losses in the start-up circuit. Because of the internal start-up switch and burst mode operation, it is possible to supply an output power of 0.5W with under 1W input power when the input line voltage is 265V. On no load condition, input power is under 0.3W. The FAN7601 offers a latch protection pin for the protection of the system e.g. over voltage protection and/or thermal shutdown. The internal over voltage protection function shuts down the IC operation when the supply voltage reaches 19V. In addition, a soft start function is provided, and the soft start time can be varied.

  • FAIRCHILD AN6012 Manual

    Application Note AN6012 Design of Power Factor Correction Circuit Using FAN7528

  • FAIRCHILD AN-8025 Manual

    This application note describes the design guidelines of a 75W universal-input, single-stage power factor correction (PFC) for LED lighting applications. It utilizes a flyback converter topology controlled by the critical conduction mode control IC, FAN7530, and incorporates several functions such as CV/CC mode feedback circuits, cycle-by-cycle current limit, soft-starting function, etc., specifically for LED lighting applications.

  • FAIRCHILD AN-6208 Manual

    This document introduces FAN6208, which is a synchronous rectification controller for isolated LLC or LC resonant converters that can drive two individual SR MOSFETs emulating the behavior of rectifier diodes. FAN6208 measures the SR conduction time of each switching cycle by monitoring the drain-to-source voltage of the SR MOSFETs.

  • FAIRCHILD BUZ11 Manual

    The BUZ11 is a 30A, 50V, 0.040 Ohm N-channel power MOSFET manufactured by Fairchild Semiconductor Corporation. It has nanosecond switching speeds, linear transfer characteristics, high input impedance and majority carrier device features.
