    Schottky Diode Selection in Asynchronous Boost Converters
    PDF, 491 Kb, Archivo publicado: sept 6, 2016
    Asynchronous boost converters require a Schottky diode as the rectifying element due to the diode's lowforward voltage and fast turn-on time. Because of these characteristics asynchronous boost converterscan have as good as, or better efficiency, than synchronous boost converters. This is especially true whenthe boost conversion ratios (VOUT/VIN) are high, and the Schottky diode conduction t
