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 ºC < Tamb < 60 ºC. 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. 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. 6 Embedded Power for Business-Critical Continuity Rev.07.20.07 vrm10 series 4 of 10 Specifications VOLTAGE IDENTIFICATION (VID) CODES VOLTAGE IDENTIFICATION (VID) CODES (CONTD.)
