NNootteess
1Recommended 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.
28 mV pk-pk ripple. Vin = 12 V, Vout = 1.35 V, Iout = 85 A.
3With 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 20 MHz bandwidth, 0 ºC < Tamb < 60 ºC.
4VRM10 uses a four phase buck topology. Each phase switches at
550 KHz. This gives an equivalent switching frequency of 2.2 MHz
5Recommended 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.
60.01 G2/Hz from 5 Hz to 20 Hz, maintaining 0.02 G2/Hz from 20 Hz to
500 Hz, all axes.
7Maximum current requires adequate forced air over the converter. Please
consult Figures 2 and 3 for thermal de-rating.
8When 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.
9Pins 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. Pb-free (RoHS 6/6) compliant versions may be available on
special request, please contact your local sales representative for details.
12 NOTICE: Some models do not support all options. Please contact your

(refer to Table 3); Rout is in Ω’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.
