This reference design describes the characteristics, operation, and use of the LED/laser driver. This driver contains our TPS92641 IC configured as a solid-state driver solution providing a 3-channel regulated current output to drive 3 solid-state devices. A high-efficiency single inductor synchronous stepdown (buck) converter topology is used. This reference design includes the driver specifications, a schematic diagram, PCB layout artworks, recommended test setup, and bill of materials to help the end user to implement the driver in their specific application.

  • High brightness
  • Low cost bill of materials (BOM)
  • Supports top-side pump architecture
  • Good performance
  • Small form factor
