Vicor Full-chip PRM-RS Customer Board - Manual

UG:009 vicorpower.com Applications Engineering: 800 927.9474 Page 1
The full-chip PRM-RS Customer Board described in this document is designed for use with the
Remote Sense (RS) family of full-chip PRM
® regulators, and demonstrates the benefits of
Factorized Power Architecture™. This demonstration board is not designed for installation in end-
user equipment. The system demonstrates the use of a PRM Regulator and a VTM
® Current
Multiplier for general laboratory evaluation only.
Please read this document before setting up a customer demonstration board.
The User Guide is not comprehensive and is not a substitute for common sense and good
practice. For example:
1. When testing electronic products always use approved safety glasses.
2. Provide a strain relief for wires and place the system on the bench in such a way as to prevent
accidental dislodgment from the bench top.
3. Remove power and use caution when connecting and disconnecting test probes and interface
lines to avoid inadvertent short circuits and contact with hot surfaces.
4. Never use a jumper in place of the fuse. Replace the fuse only with its equivalent type
and rating.
5. Never attempt to disconnect the demonstration board from a VTM Customer Board while
power is applied. This system is not designed to demonstrate hot plug capability.
1.0 Introduction
The full-chip PRM-RS Customer Board can be used to demonstrate a stand-alone regulator or in
conjunction with a VTM Customer Board to enable demonstration of a Factorized Power
Architecture (FPA) system. There are many combinations possible using PRM and VTM Customer
Boards, but the focus in this user guide is using one PRM Customer Board and one VTM
Customer Board. The full-chip PRM Customer Board can be configured for local sensing (at the
PRM output), or non-isolated remote sensing (at the VTM module output). The full-chip PRM
Customer Board is nominally configured for local sensing where the voltage feedback circuit
regulates the output voltage of the PRM module. Implementing remote sensing requires
component changes and rework to the board which is detailed in section 8.3.
1.1 Part Numbers and Ratings
Refer to the specific PRM module data sheet for ratings of the device. It is important to remain
within the device limits when testing.
