PRODUCT SPECIFICATION

Electrical Speciﬁcations (Continued)

(V_CCA= 5V, V_CCP= 12V, V_OUT= 2.0V, and T_A= +25°C using circuit in Figure 1 unless otherwise noted.)

The • denotes speciﬁcations which apply over the full operating temperature range.

Notes:

1. Steady State Voltage Regulation includes Initial Voltage Setpoint, Droop, Output Ripple and Output Temperature Drift and is

measured at the converter’s VFB sense point.

2. As measured at the converter’s VFB sense point. For motherboard applications, the PCB layout should exhibit no more than

0.5mΩ trace resistance between the converter’s output capacitors and the CPU. Remote sensing should be used for optimal

performance.

3. Using the VFB pin for remote sensing of the converter’s output at the load, the converter will be in compliance with Intel’s VRM 8.4

specification of +50, –80mV. If Intel specifications on maximum plane resistance from the converter’s output capacitors to the CPU

are met, the specification of +40, –70mV at the capacitors will also be met.

4. Actual output voltage (V

) at 0A load is 1ꢀ higher than specified in the “Typical” column.
