1 2 3 Recommended output capacitance, 12 x 560 F aluminium polymer and 44 x 10 F MLCC for slew rates up to 430 A/s, 14 x 560 F aluminum polymer and 45 x 10 F MLCC for slew rates up to 930 A/s. 8 mV pk-pk ripple. Vin = 12 V, Vout = 1.35 V, Iout = 85 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 100 A for the VRM10-85-12-UY (91 A for the VRM1080-12-PY) over a 20MHz bandwidth, 0 C < Tamb < 60 C. 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 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 VRM10-85-12UY, do not leave these pins floating. 10 When included in the users system ESD event shall cause no out-ofregulation conditions. 11 The `Y' suffix indicates that these parts are TSE RoHS 5/6 (non Pb-free) compliant.

For the LFM and VID conditions graphed, there is no derating between 0 C and 25 C. 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.
