LED’s for Automotive Applications LED’s for Automotive Applications

LEDs in battery operated applications controlling brightness power efficiently, white light-emitting diode (LED) drivers provide high efficiency and brightness matching for LCD backlighting in displays. To control brightness, these drivers regulate current going into LEDs that are arranged in either serial or parallel configuration. Charge pumps drives parallel LEDs whose currents are regulated with individual regulators or simple ballast resistors
