Digital controlled light source driving apparatus

摘要

A digital controlled light source driving apparatus includes a digital processor and a step-up circuit. The digital processor has a digital switching-signal generating module and a protecting module. The digital switching-signal generating module generates at least one digital switching signal set. The protecting module generates one protecting switching signal set according to the digital switching signal set. The step-up circuit is electrically connected to the protecting module and generates a power signal according to the protecting switching signal set.
