Notes

A

For the LFM and VID conditions graphed, there is no derating between 0 ºC

and 25 ºC.

B

For load regulation equations: VID is in Volts, programmed by the VID bits

(refer to Table 3); Rout is in

and 0.038 for VRM10-80-12-PY.

C

Efficiency Vs load plotted is representative of a typical VRM10-85-12-UY with

VID = 1.4 V, LL0 = 0, LL1 = 1.

D Shown for a VRM10-80-12-P with VID = 1.4 V.
