Comments

IRMS = 5.4A @ 65°C

ESR ≤ 13mΩ

DCR ~ 3mΩ

See Note 1.

DCR ~ 2mΩ

RDS(ON) = 17mΩ @

VGS = 4.5V

RDS(ON) = 6.5mΩ @

VGS = 10V

Notes:

1. Inductor L1 is recommended to isolate the 12V input supply from noise generated by the MOSFET switching. L1 may be

omitted if desired.

2. For a spreadsheet on MOSFET selections, refer to Applications Bulletin AB-8.
