Info!! Tin Forcefulness Out A Dual Output Dc-Dc Converter Supply A Unmarried Output?

Yes, many dual output DC-DC converters tin genuinely survive used to provide a higher voltage, unmarried output.

Figure 1 shows a simplified block diagram of the TDK-Lambda’s CCG +/-12V dual output converter.  Two transformer secondary windings are rectified in addition to filtered to provide ii 12Vdc voltages in addition to are connected together, effectively inwards series.  Internally the 0V of the upper circuit is connected to the +12V of the lower circuit in addition to this betoken is supplied to the user every bit the 0V or mutual connection.  This provides a +12V in addition to a -12V output to the user.

Figure 1: Influenza A virus subtype H5N1 dual output DC-DC converter providing a +/-12V output

If a unmarried 24V output voltage is needed, a dual output converter tin survive used every bit shown inwards Figure 2.

Figure 2: Influenza A virus subtype H5N1 dual output DC-DC converter providing a 24V output

Internally cipher has changed, at that spot are however ii 12Vdc voltages connected inwards series.  If the mutual final is non connected to the user’s circuit, the converter tin at in 1 lawsuit provide a 24V unmarried output.

Note the maximum available output electrical current remains the same every bit the maximum output electrical current of the dual output converter.  For event the 30W CCG30-24-12D is rated at +/-12V +/-1.25A, important it is capable of supplying +12V at 1.25A in addition to -12V at 1.25A or if connected every bit a unmarried output, 24V at 1.25A (30W).

Likewise a dual output +/-15V converter tin survive configured to render 30V.

Always confirm amongst the manufacturer if their datasheet does non soil it tin survive used every bit a unmarried output.
