REV. 1.1.0 3/27/03
Electrical Specifications
(V
CC
= 12V, VID = [01111] = 1.475V, and T
The
denotes specifications which apply over the full operating temperature range.
A
= +25°C using circuit in Figure 2, unless otherwise noted.)
Notes:
1. As measured at the converter’s VFB sense point. For motherboard applications, the PCB layout should exhibit no more than
0.5m
trace resistance between the converter’s output capacitors and the CPU. Remote sensing should be used for optimal
performance.
2. Using the VFB pin for remote sensing of the converter’s output at the load, the converter will be in compliance with VRM 9.x
specification.
