DN-77 Overcurrent Shutdown with the UC3853
PDF, 44 Кб, Файл опубликован: 5 сен 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

U-159 Boost Power Factor Corrector Design with the UC3853
PDF, 466 Кб, Файл опубликован: 5 сен 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
