Automotive Lighting

From headlights to LCD backlighting in infotainment systems, LEDs are an integral part of the driving experience. National's portfolio of LED drivers offer key features like PWM dimming, accurate under-voltage lockout (UVLO), and high-side current sensing. Plus, low LED ripple current and external oscillator sync capabilities allow designers to reduce issues with EMI. These LED drivers provide maximum efficiency and effectiveness in any automotive lighting system.

National's family of PowerWise® high-brightness LED drivers power the new generation of 1W-to-5W high-brightness LEDs found in automotive applications such as headlights, taillights, signaling, daytime running lights, interior lighting, and infotainment backlighting.

National LED drivers for automotive applications provide

• Wide input voltage range
• Constant current to regulate the LED brightness
• Low feedback voltage for minimized power dissipation

Furthermore, National's portfolio offers dimming, protection, and thermal control features suitable for a wide range of applications.

Online tools such as reference designs, application notes, and National’s LED WEBENCH® online design tool allow for quick and easy selection and simulation of a complete LED and LED driver solution.

Additionally, National offers a range of thermal management solutions. These temperature sensors monitor lighting systems to ensure reliability and robustness.
