Find Designs, Fast

About Reference Design Library

Instead of searching many manufacturer sites or calling on companies to find and compare designs, now you can search for designs based on the circuit’s performance using Digi-Key’s Reference Design Library.

The Reference Design Library was created in order to:

  • Save Engineers time
  • Deliver ideas, fast
  • Sift through designs based on performance
  • Provide designs conveniently accompanied by their schematics

Visit often as new designs are being added weekly and improvements will be made based on your constructive feedback.

FSUSB242GEVB: USB Type-C Port Protection Switch

Manufacturer: ON Semiconductor

The FSUSB242GEVB is an evaluation board for the FSUSB242 USB switch that provides high voltage and surge protection for the HSD+/HSD- lines. Electrical surge is an increasing concern for small form factor connectors such USB microB and USB Type-C™. This evaluation board will demonstrate 2:1 switching while maintaining sufficient signal integrity so the USB 2.0 HS eye diagram can still be passed.

STEVAL-LLL008V1: 100W, 1.4A @ 70V 90 ~ 265 VAC, 6LoWPAN Mesh Networking

Manufacturer: STMicroelectronics

The STEVAL-LLL008V1 reference design is a dual-stage LED driver with high power factor designed for 100 W LED lighting applications using 6LoWPAN Mesh networking. The front-end flyback converter provides high power factor and low THD and implements CV primary side regulation (PSR) with input from an auxiliary winding on the transformer through the ZCD pin on the HVLED001B controller, so no isolated optocoupler is required. The flyback converter can deliver 105 W with an average 79 V output.
