Si88xx Isolator Evaluation Kit
The Si88xx evaluation kit allows customers to evaluate the performance of the Si88xx digital isolators with integrated dc-dc converter family of products. The evaluation board has the Si88241ED-IS populated to showcase the family. It is a complete solution for using a 3 - 5 V primary supply to deliver up to 2 W on the secondary side at 3 - 5 V supply voltage. Convenient test points are included to measure and observe time varying currents and voltages to calculate relevant parameters like efficiency, load/line regulation etc.
