    DN-77 Overcurrent Shutdown with the UC3853
    PDF, 44 Kb, Archivo publicado: sept 5, 1999
    Boost converters are susceptible to large inrush currents at startup and with step changes in VLINE, because the output capacitor is connected directly to the input through the boost diode. This design note describes and provides a schematic for a circuit that provides overcurrent shutdown using the UC3853 High Power-Factor Preregulator. The UC3853 provides simple yet high-performance active power

    DN-78 UC3853 Demo Board
    PDF, 204 Kb, Archivo publicado: sept 5, 1999
    This design note describes a demo board for the UC3853 8-pin, High Power-Factor Preregulator Integrated Circuit. This demo board was designed for 100W, 75kHz operation over a universal input-voltage range (80VAC to 270VAC). A parts list and schematic diagram for the typical application circuit are included in this design note.

    U-159 Boost Power Factor Corrector Design with the UC3853
    PDF, 466 Kb, Archivo publicado: sept 5, 1999
    The UC3853 provides high-performance power-factor correction (PFC) for low- to medium-power applications with minimal complexity. It provides power supplies in the range of 10-200W with a low-distortion, power-factor-corrected input current, a regulated output voltage, and operation over a wide range of input voltages. The UC3853 uses average current mode control and works with either a boost or f
