Next, place the input and output capacitors. Position one high-
frequency ceramic input capacitor next to each upper
MOSFET drain. Place the bulk input capacitors as close to the
upper MOSFET drains as dictated by the component size and
dimensions. Long distances between input capacitors and
MOSFET drains result in too much trace inductance and a
reduction in capacitor performance. Locate the output
capacitors between the inductors and the load, while keeping
them in close proximity to the microprocessor socket.

Voltage-Regulator (VR) Design Materials
The tolerance band calculation (TOB) worksheets for VR
output regulation and IMON have been developed using the
Root-Sum-Squared (RSS) method with 3 sigma distribution
point of the related components and parameters. Note that
the “Electrical Specifications” table beginning on page 8
specifies no less than 6 sigma distribution point, not suitable
for RSS TOB calculation. Intersil also developed a set of
worksheets to support VR design and layout. Contact
Intersil’s local office or field support for the latest available
information.
