The polarity-protection circuit in Figure 1 is a high-performance alternative to the usual series diode (often Schottky). The circuit incurs a much lower voltage drop than even the best Schottky diode. The circuit uses MOSFET devices because of ...
Christian Rausch EDN Designers use ballast ICs, such as International Rectifier’s IR53HD420 , in CFLs (compact fluorescent lamps) for heating the filaments, igniting the lamps, and supplying the lamps with current. Manufacturers produce these ...
Jim Walker Electronic Design When a circuit requires reverse-voltage protection on the power input, the usual approach is a series diode (see the figure, a). But if the input voltage is low say, two or three AA batteries the 0.5-V loss of a ...
Double-Anode MOSFET Thyristor Michael Shustov, Andrey Shustov, Tomsk A double-anode MOSFET thyristor circuit with UHS, high input impedance, and extremely low losses is proposed. Thyristor (triac) load switches, by force of nonremovable specific ...
Application Note AN-1188 August 2013 Akos Hodany The IRuFB1 40 W Isolated Flyback PFC design is presented in this document. This power supply circuit provides power factor correction (PFC), output voltage regulation and full protection against ...
Application Note AN-1187 Alex Lollio The IR3230 is a three-phase brushless DC motor controller/driver with many integrated features. They provide large flexibility in adapting the IR3230 to a specific system requirement and simplify the system ...
