Vehicle lighting has become more demanding with different load requirements, strict Electromagnetic Compatibility (EMC) requirements, accuracy requirements, and power consumption requirements. These requirements are all under the constraint of ever shrinking PCB’s driving up the cost of PCB real estate. Pulse width modulation (PWM) is used to control the interior and exterior lighting in vehicles and meet all these requirements. One or more electronic control units in the body domain of a vehicle contain a number of integrated circuits that drive loads using PWM signals. In addition to driving loads, PWM signals are used for things such as dimming and diagnostic functions. In current technology the PWM signal is usually composed of a trapezoidal wave or rounded wave which control bulbs and light emitting diodes (LED) loads in a vehicle.
