(Components based on Worst Case Analysis—See Appendix for Details)
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 35A 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.
