Abstract
In general,PWM control chip is shut down in case of VCC undervoltage. According to this feature, the short-circuit or over current protection circuit in LED power supply has been proposed in this paper. By means of reducing VCC voltage or turning off the PWM output, the two Low-cost short-circuit protection circuits have been designed.关键词
