Figure 4
— EVAL Board Schematic Diagram
The functionality of the FPAEval Board has now been
verified
over the entire line and load operating range.
As you can see, the PRM’s Adaptive Loop regulates the output
of the VTM without sense lines. You may monitor the Vf View
(J1) while increasing the load current: the Vf voltage increases
with the load current, compensating for the insertion loss due
to the VTM output resistance.
Connecting the PRM’s PC (TP1) to the -IN disables the output
of the Evaluation Board. Use CAUTION when probing,
especially on or near TP1 and VC on the PRM. Accidental
shorting between these two points can cause permanent
damage.
The Evaluation Board has provisions for changing the factory
set output voltage, the current limit, the Adaptive Loop Gain,
and the turn on ramp rate. Refer to the PRM data sheet for
more information on these features. Refer to Figure 4 for a
Schematic representation of the FPAEvaluation Board.
Locations for these components are shown in Figure 3.
