8. DESIGN INFORMATION
8.1 Reference Design
This W55MID15 application schematic is subject to modify for target specification evaluation. Some
components are due to system specification evaluation purpose only which will be removed once the
system evaluation is done. The magnetic field coupling strength is subject to the appropriate value of
inductor and capacitor.
8.1.1 Demo Board
fop
13.56MH
The value of "L" will depend on PCB coil layout
and the value of "C" needs to fine-tune and
matches the magnetic field resonance center f_OP
= 13.56 MHz
