EVM Setup and Precautions
2 EVM Setup and Precautions
2.1 Power Supply Connections
Figure 1 illustrates the EVM power supply schematic.
Figure 1. ISO5851 EVM Power Supply Schematic
The primary side of the EVM (V
CC1
) operates from a single 3-V to 5.5-V power supply and connected via
TB3. Test point (TP8) is available for monitoring the primary power supply.
The EVM provides connections for evaluating the output side (V
CC2
, V
EE2
) with either a bipolar or unipolar
power supply, from a minimum 15-V to maximum 30-V. For unipolar operation, connect V
EE2
to GND2
through a wire-bridge between pin 2 and pin 3 of TB2, as shown in Figure 2 . V
CC2
and V
EE2
can be
monitored via TP17 and TP19, respectively.
