智能的固态保险丝治愈升压转换器的弊病

异步、 基于电感升压转换器 （升压开关类型） 的大部分展品直流电流路径之间的电源与负载 （图 1）。此路径可以有两个不良后果： 第一，如果接地的输出或其他过载绘制沉重的输出电流为几个几百毫秒，catch 二极管 （通常肖特基类型） 可以散发出铁水硅和所有真正的黑客花盆复合熟悉该混合的香气。第二，如果切换操作禁用任何原因，如故意关机、 负载电压仍是电源电压只有一个二极管下降。这可能导致不确定此剩余电压应负载电路预期稳定状态的工作范围外的电路行为。

APPLICATION NOTE 715
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
