Starting from scratch
If you are starting from scratch, see our reference design LEDFRONTHBLB_REF. The design guide describes the implementation of an automotive front light high beam/low beam combination in detail. It uses the flexible multi-topology DC-DC controller TLD5099EP of the LITIX™ Power family in the current-controlled buck-boost SEPIC configuration.
myInfineon: Join now and enjoy the benefits
- Lighting applications are changing and there is the demand of more sophisticated pixel light sources. The new light sources need a different approach on the power supply and TLD5501-2QV covers the gap with the existing architectures. Moreover the TLD5501-2QV is also the preferred solutions for high intensity LED or Laser used in premium.
- To promote the device two evaluation boards are available. The device has been also included into DC-DC designer to reduce the design-in phase. Low level drivers are available to reduce the coding effort.
The TLD6098-2DPVB2G evaluation board is a dual-phase boost-to-ground switching power supply, which, under nominal conditions, can deliver a constant voltage of 43-52 V and a current of up to 7A.
