Board Operating Modes
PRM evaluation board supports both Adaptive Loop and Remotes Sense Operation.
Therefore, operating mode selection switch S10 is provided on the board for selection of
the following operating modes:
n Default / Adaptive loop using PRM
n Adaptive loop using PRM and VTM
n Remote Sense: local sensing (single ended)
n Remote Sense: non-isolated remote sense (differential)
n Slave (for array operation)
