NOTES
1. V
IN
= 12Vdc, T
A
= 25ºC, Airflow =
400LFM unless otherwise noted.
2. The output impedance is 1.25mΩ.
3. Output ripple voltage is specified when measured
with Intel
®
specified capacitance at the output of
the converter.
4. Transient response is specified with Intel
®
speci-
fied capacitors at the output of the converter.
5. If remote sense is not required or used,
the Sense(+) and Sense(–) pins must be con-
nected to Vo(+) and Vo(–) respectively.
6. 10μF ceramic X5R or X6S.
7. VRM_PRES and VRM_ID are connected to V
SS
on
the VRM through a 100Ω resistor.
8. LL0, LL1 gives 1.25mΩ load line only.
