PI2003-EVAL1 Datasheet, PDF (2/8 Pages) Vicor Corporation – PI2003-EVAL1 Active ORing
Cool-ORingTM PI2003 Product Description
The Cool-ORing PI2003 with an external industry standard
100V N-channel MOSFET provides a complete Active ORing
solution designed for use in -48 Vbus redundant power
system architectures. The PI2003 controller with an N-channel
MOSFET enables extremely low power loss with fast dynamic
response to fault conditions, critical for high availability
systems.
The PI2003 controller with a low Rds(on) N-channel MOSFET
provides very high efficiency and low power loss during
steady state operation. The PI2003 controller provides an
active low fault flag output to the system during excessive
forward current, light load, or reverse current.
Figure 1 shows a photo of the PI2003-EVAL1 evaluation
board, with two PI2003 controllers and two N-channel
MOSFET used to form the two Active ORing channels. The
board is built with two identical Active ORing circuits with
options and features that enable the user to fully explore the
capabilities of the PI2003 universal Active ORing controller.
