Note: The following information is given as a hint for the implementation of the device only and shall not be
regarded as a description or warranty of a certain functionality, condition or quality of the device.
This application note intends to provide information about duty cycle determination, necessary to drive lamps in
PWM, function of the measured battery voltage.
.The purpose of the PWM is to maintain the light emited by the lamp constant, regardless of the battery voltage
applied. Maintaining a constant light has for consequence to maintain the electrical power constant.
