Table 3. RC5058 Application Bill of Materials for Intel Coppermine/Camino Motherboards
(Typical Design)
Notes:
1. Inductor L1 is recommended to isolate the 5V input supply from noise generated by the MOSFET switching, and to comply
with Intel dI/dt requirements. L1 may be omitted if desired.
2. For 12.5A designs using the TO-220 MOSFETs, heatsinks with thermal resistance
Θ
SA
< 20
°
C/W should be used. For
designs using the TO-263 MOSFETs, adequate copper area should be used. For details and a spreadsheet on MOSFET
selections, refer to Applications Bulletins AB-8 and AB-15.
