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-

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
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.
