Vicor VI Chip PRM Evaluation Board - Manual (Page 2)

The PRM ® evaluation board can be used to demonstrate a stand-alone buck-boost
regulator or in conjunction with a VTM evaluation board to enable evaluation of a
Factorized Power Architecture
™ (FPA) system. There are many combinations possible
using PRM and VTM evaluation boards, but the focus in this user guide is using one
PRM evaluation board and one VTM evaluation board, with a brief overview of how to
parallel boards.
The PRM module evaluation board can be used to configure various modes of
regulation depending upon the application requirements. (1) AL Operation: the PRM
uses a unique feed-forward scheme that enables precise regulation of an isolated
POL voltage without the need for remote sensing and voltage feedback. (2) Remote
Sense Operation: the internal regulation circuitry is disabled and an external control
loop and current sensor maintain regulation. This affords flexibility in the design of
both voltage and current compensation loops to optimize performance in the end
application. In Remote Sense Operation, PRM can be set in local sense mode or in
non-isolated remote sense mode depending on the application.

Refer to the specific PRM data sheet for detail ratings of the device. It is important to
remain within the device limits when testing.
These boards make it convenient to evaluate the performance of Vicor’s PRM products.
All evaluation boards include sockets to allow easy "plug and play" insertion and
removal of through-hole components and wires while providing kelvin voltage
measurements test points of all pins of the PRM. Evaluation boards are designed to
simplify testing of the product by providing test points and sockets for easy connection
to standard test-equipment, lugs for input/output connections, connectors to allow easy
insertion and removal of the PRM evaluation board and VTM evaluation board.
