Abstract

<B> CIRCUITO ELETRÈNICO PARA DISPOSITIVO ELETRÈNICO PORTáTIL <D>. Circuito eletrónico (200) para um dispositivo eletrónico portátil inclui uma interface (202) de fonte de energia, uma carga (204) acoplada à interface (202) de fonte de energia, um circuito (206) de armazenamento de energia tendo uma voltagem de operação máxima, e um circuito de comutação (208). O circuito de comutação (208) é acoplado à interface (202) de fonte de energia em série com o circuito (206) de armazenamento de energia. O circuito de comutação (208) opera para desacoplar comutavelmente o circuito (206) de armazenamento de energia em resposta a uma voltagem na carga (204) que excede a voltagem de operação máxima.
