BLOCKING and FREE WHEELING DIODES:
The Peak Reverse Voltage ratings should be a minimum of 2-3 times the power supply
maximum output voltage. The Continuous Forward Current rating should be a minimum of
1.5 times the power supply maximum output current. Heatsink may be required. There also
may be a need for higher voltage rated parts, dependent on load circuit design and inductor
values.
Connecting to the Load in Local Sensing Mode
Connect the negative (-) output terminal of one power supply to the positive (+) output
terminal of the next power supply. See Figure 15 for a representation of series operation.
