Board Layout
DC1204A is a 2-layer board. The inputs and outputs
of the two ideal diode circuits are entirely independ-
ent, sharing only a common ground. Banana jacks
are provided for input and output connections; tur-
rets facilitate connection of voltmeters and scope
probes.
Modifying for More Current
You cannot modify DC1204A for higher current lev-
els. If currents greater than 5A are needed, use the
LTC4357 positive high voltage ideal diode controller
featured on DC1203A.
