14. OUTPUT SERIES CONNECTIONS
Two or more converters can be connected in series to obtain a higher output voltage. To prevent output reverse biasing each other in
case of a short, add a Schottky diode on each output in reverse polarity, as shown in the diagram. In the event of a short, the con-
verters will forward-bias the diodes and the output reversal will be limited to one diode drop (about 0.5V) only, so as not to damage
the converters. The forward current will cause each converter to go into short-circuit protection.
sure that: 1) the diodes voltage rating is higher than each converter output; 2) the rated diode current can carry the short-circuit cur-
rent; 3) the diodes do not overheat before the short is removed.
15. REMOTE OUTPUT ON/OFF CONTROL
The converter output can be enabled or disabled through the On/Off pin. The control logic is shown in this table. A common control
circuit is shown below. The standard version defaults to positive logic. For negative logic, indicate the selection when ordering.
16. ISOLATION
The input and output of the converter are electrically isolated. If needed, an output terminal can be connected to an input terminal,
resulting in the converter non-isolated.
