Table 2. RC5057 Application Bill of Materials
(Components based on Worst Case Analysis—See Appendix for Details)
*See Appendix.
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 designs using the TO-220 MOSFETs, heatsinks with thermal resistance
ΘSA < 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 Bulletin AB-8.
