Table 2. FAN5093 Application Bill of Materials for Figure 1
Notes:
1. Inductor L1 is recommended to isolate the 12V 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 designs using the TO-220 MOSFETs, heatsinks with thermal resistance
θSA < 20°C/W should be used. For details and a
spreadsheet on MOSFET selections, refer to Applications Bulletin AB-8.
*Output capacitance requirements depend critically on layout and processor type. Consult Application Bulletin AB-14 for details.
See the Appendix to this datasheet for the method of calculation of these components. Pin 5 must be used to remote sense the
voltage at the processor to achieve the specied performance.
