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.
Recommended products for this segment are:
- TLD5542-1 (buck-boost controller with SPI)
- 2 x IPG20N04S4-12 (40V, Dual N-Ch, 8.6 mΩ max)
- Traveo™ II

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.
Recommended products for this segment are:
- TLD5190 (buck-boost controller)
- IPG20N06S4L-26

Entry-level headlamps (Class B) - electronic designs are typically based on a minimized BOM (bill-of-materials):
- 3-5 LEDs within total < 15W
- Asynchronous DC-DC converters
Recommended products for this segment are:
- TLD5099EP (boost controller)
- IPD15N06S2L-64
Switches for PWM Dimming of the LED chain:
Reverse polarity protection:
IPD50P03P4L-11 (-30V, P-Ch, 10.5 mΩ max)
- LITIX™ the best LED Driver IC
- 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 and for general voltage supply
- OptiMOS™ single- and dual N-channel and P-channel MOSFETs as a perfect complement to LITIX™ Power and Power Flex DC-DC LED driver controller.
The micro learning is an introduction to LITIX™ power devices for two-wheeler headlamp applications. It explains the two-wheeler market concept and shows the different motorcycle applications. In addition, it explains the key features of the three main segments and how the motorcycle LED headlamps work.
The microlearning shows the LITIX™ power family devices for motorcycle applications. The LITIX™ power family provides easy-to-use devices available for headlamp and the training explains why they are the best-fit solution for each of the segments
The microlearning shows the key features of only using a single DC-DC controller in order to achieve the desired light function. It also shows how to lower costs and have fewer components, among other improvements, with the same current for both LED strings. In addition, it explains how the system manages the three light functions with just two switches.
