The VRM10 non-isolated DC-DC converters are designed to meet
the exceptionally fast transient response requirements of today’s
microprocessors and fast switching logic in a compact size at a
very affordable price. Advanced circuit techniques, component
selection and placement optimization, state-of-the-art thermal
packaging, and surface-mount technologies provide a high power
density, highly reliable, and very precise voltage regulation system
for advanced microprocessors.

Notes
1 Recommended output capacitance, 12 x 560 μF aluminium polymer and 44 x
10 μF MLCC for slew rates up to 430 A/μs, 14 x 560 μF aluminum polymer
and 45 x 10 μF MLCC for slew rates up to 930 A/μs.
2 8 mV pk-pk ripple. Vin = 12 V, Vout = 1.35 V, Iout = 85 A.
3 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 100 A for the VRM10-85-12-UY (91 A for the VRM10-
80-12-PY) over a 20MHz bandwidth, 0 ºC < Tamb < 60 ºC.
4 VRM10 uses a four phase buck topology. Each phase switches at
550 KHz for the VRM10-85-12-UY and VRM10-80-12-PY. This gives an
equivalent switching frequency of 2.2 MHz. For the VRM10-105-12-EJ, each
phase switches at 275 KHz. This gives an equivalent switching frequency of
1.1 MHz
5 Recommended input fusing: one 20 A (or two 10 A in parallel) very fast
acting fuse(s). The VRM10 is a high current device. Use appropriate
care in handling and installation of this device, which is intended only for use
within enclosed equipment.
6 0.01 G2/Hz from 5 Hz to 20 Hz, maintaining 0.02 G2/Hz from 20 Hz to 500
Hz, all axes.
7 Maximum current requires adequate forced air over the converter. Please
consult Figures 2 and 3 for thermal de-rating.
8 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 a crowbar device.
9 Pins 12 and 51 are not connected on VRM10-80-12-PY. On VRM10-85-12-
UY, do not leave these pins floating.
10 When included in the users system ESD event shall cause no out-of-
regulation conditions.
11 The ‘Y’ suffix indicates that these parts are TSE RoHS 5/6 (non Pb-free)
compliant.

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 W’s, programmed by the LL bits (refer to Table 1);
and the output current, Iout is in amps. VWindow is 0.040 for VRM10-85-12-UY
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.
