A Smart Solid-State Fuse Cures Boost-Converter Ills
The majority of asynchronous, inductor-based boost converters (the step-up switching types) exhibit a DC-
current path between power source and load (Figure 1). This path can have two undesirable consequences:
First, if a grounded output or other overload draws heavy output current for more than a few hundred
milliseconds, the catch diode (usually a Schottky type) can exude that blended aroma of molten silicon and
potting compound familiar to all true hackers. Second, if switching action is disabled for any reason, such as
intentional sh……
