Figure 11. Typical circuits
Figure 12. Test method of the board having fuse and Trisil
These topologies, using SMP100MC from ST and TCP1.25 A from Cooper Bussmann, have
been functionally validated with a Trisil glued on the PCB. Following example was performed
with SMP100MC-270 Trisil. For more information, see Application Note AN2064.
