Table 2. RC5058 Application Bill of Materials

(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 17.4A designs using the TO-220 MOSFETs, heatsinks with thermal resistance

Θ

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.

*Refer to Appendix for values.
