Increasing Output Voltage and Current Range Using SeriesConnected Isolated ВµModule Converters вЂ“ Design Note 530
Jesus Rosales and Willie Chan
Linear TechnologyвЂ™s isolated ВµModule В® converters
are compact solutions for breaking ground loops.
These converters employ a flyback architecture whose
maximum output current varies with input voltage and
output voltage. Although their output voltage range
is limited to a maximum of 12V, one can increase the
output voltage or the output current range. The solution simply involves connecting the secondary side
of two or more isolated ВµModule converters in series.
The LTM В®8057 and LTM8058 UL60950-recognized
2kV AC isolated ВµModule converters will be used to
demonstrate this design approach, which can also be
applied to the LTM8046, LTM8047 and LTM8048. LetвЂ™s
assume an output of 10V at 300mA is desired from
a 20V input. Reviewing the maximum output current
curve from Figure 1, we notice that a single LTM8057
is insufficient to meet the output current requirement
under these conditions.
However, upon noticing that a single LTM8057 can
deliver 300mA at 5V from a 20V input, a solution becomes apparent. Since the output voltage is isolated
from the input, the outputs of two LTM8057s set at
5V can be connected in series to achieve a 10V output …
