The AMD VRM non-isolated dc-dc converter is designed to meet
the exceptionally fast transient response requirements of today’s
microprocessors and fast switching logic in a compact size at an
affordable price. Advanced circuit techniques, component
selection, placement optimization, and state-of-the-art silicon
integration thermal packaging, provide a high power density,
highly reliable, and very precise voltage regulation system for
advanced microprocessors.

Recommended output capacitance, 48 x 22 μF ceramic MLCC.
50 mV pk-pk ripple. Vin = 12 V, Vout = 1.5 V, Iout = 80 A.
With the recommended capacitors (See Note 1) across the output, the
output voltage stays within the load regulation window for all loads and
transient events, up to 80 A. It will also allow instantaneous VID-on-the-fly
changes of up to 500 mV at 80 A.
VRM64 uses a five phase buck topology. Each phase switches at
830 kHz. This gives an equivalent switching frequency of 4.2 MHz
Maximum current requires adequate forced air over the converter. Please
consult Figure 1 for thermal derating.
When the VRM detects an output over-voltage event, the OVP pin
transitions to logic high. This signal can be used to shut down the supply to
the VRM, or drive an external crowbar device.

NOTES AND CONDITIONS
Vin = Vin (typ.),
Iout (cont.) = 80 A, VID = 1.5 V
These are default settings. The current limit may be set to ‘trip’ or
‘hiccup’. The output overvoltage limits, input overvoltage and undervoltage
settings, the output droop and offset, the current limit setpoint and many
others can be changed by component changes. Please consult the factory
for details.
8 0.01 G2/Hz from 5 Hz to 20 Hz, maintaining 0.02 G2/Hz from 20 Hz to 500
Hz, all axes.
9 In accordance with AMD requirements, PWRGD will go high at least 2 ms
after VDD settles within specifications.
10 The ‘Y’ suffix indicates that these parts are TSE RoHS 5/6 (non Pb-free)
compliant. Pb-free (RoHS 6/6) compliant versions may be available on special
request, please contact your local sales representative for details.
11 NOTICE: Some models do not support all options. Please contact your local
Artesyn representative or use the on-line model number search tool at
