摘要
A PWM control circuit for a driving chip and an LED driving chip for an automotive reading lamp are compatible to existing car interior lighting solutions, that is, PWM signals output by MCUs are used to turn on and off LEDs. Also provided is a PWM signal automatically generated within a driving chip and used to control the lighting status of an LED. By using PWM signals generated internally in chips to control LEDs, MCUs can be unburdened from complicated operation, and thereby can operate with improved efficiency.
