Figure 12. Test method of the board with fuse and Trisil
These topologies, using SMP100LC from ST and TCP1.25A from Cooper Bussmann, have
been functionally validated with a Trisil glued on the PCB. Following example was performed
with SMP100LC-270 Trisil. For more information, see Application Note AN2064.
