www.pearsonhighered.comPower semiconductor devices constitute the heart of modern power electronic apparatus. ... As a result, the diode has a lower conduction drop (typically 0.5 V) and faster switch-ing time, but the limitations are a lower blocking voltage (typically up to 200 V) and higher leak-age current. For example, the International Rectifier Schottky diode ...

Housed in a SO8 package, the circuit minimizes the number of external components and drastically simplifies the PFC implementation. It also integrates high safety protection features that
AN-1484Designing A SEPIC Converter - Semiconductor …
www.ti.comIn a SEPIC converter, when the power switch Q1 is turned on, the inductor is charging and the output current is supplied by the output capacitor. As a result, the output capacitor sees large ripple currents. Thus the selected output capacitor must be capable of handling the maximum RMS current. The RMS current in the output capacitor is: (14 ...
