About

Reliable LED drivers for two- and three-wheeled electric vehicles

Infineon offers reliable and efficient LED driver solutions for light electric vehicles such as electric motorcycles, motor scooters, kick scooters, and rickshaws.

Auxiliary functions: Dimming and reverse polarity protection

Switches for PWM dimming of the LED chain:

  • BSS606N
  • AUIRLL024Z

Reverse polarity protection: 

  • IPD50P03P4L-11 (-30 V, P-Ch, 10.5 mΩ max)

  • LITIX™ Power: DC-DC controller and converter optimized for medium- to high-power LED operations and for general voltage supply
  • LITIX™ Power Flex: DC-DC controller optimized for high-efficiency and high-power LED operation as well as for general voltage supply
  • OptiMOS™ single- and dual N-channel and P-channel MOSFETs: Perfect complement to LITIX™ Power and Power Flex DC-DC LED driver controller

High-end with LED Pout > 35 W

High-end headlamps (Class C&D) LED drive modules to focus on design and performance:

  • Microcontroller for welcome functions, fading, etc.,
  • More than 10 LEDs within total  >35 W for a high lumen output
  • Daytime running light by a dedicated LED string
  • DC-DC buck-boost topology for a better load dump or cranking performance
Middle-range with LED Pout 15-35 W

Mid-level headlamps (Class C&D) focus on efficiency. Mileage per liter is an important selling point for the OEMs. Therefore, the focus lies on more efficient LED driver modules with synchronous DC-DC converters:

  • Same lumen output as for high-end two-wheelers
  • Daytime running lights may be using the same LEDs as high or low beam lights
  • DC-DC buck-boost topology for a better load dump or cranking performance.
Entry-level with LED Pout <15 W

Entry-level headlamps (Class B) - electronic designs are typically based on a minimized BOM (bill of materials):

  • 3-5 LEDs within total < 15 W
  • Asynchronous DC-DC converters
