•
Enter AC input voltage range and line frequency, VAC_MIN [B3],
VAC_MAX [B4], LINEFREQ [B6]
•
Enter input capacitance, CAP_INPUT [B7]
• 3
µ
F / W for universal (85-265 VAC) or single (100/115 VAC) line.
A more aggressive value of 2

ment
•
Use 1
µ
F/W for 230 VAC or for single (185-265 VAC) line. If this
cell is left blank then the capacitance value for a VMIN of 70 V
(universal input) or 150 V (single 230 VAC) is calculated. Often
this will lead to an optimal input filter capacitance value
•
Enter nominal output voltage, VOUT [B8]
•
Enter desired cable drop compensation, PERCENT_CDC [B9]
•
“0%” for no cable compensation
•
“1% - 6%” for featured H-code trim
•
Enter continuous output current, IOUT [B10]
•
Enter efficiency estimate, EFFICIENCY [B12]
•
0.83 for universal input voltage (85-265 VAC) or single 100/115
VAC (85-132 VAC) and 0.85 for a single 230 VAC (185-265 VAC)
design. Adjust the number accordingly after measuring the
efficiency of the first prototype-board at max load and VACMIN
•
Select power supply enclosure, ENCLOSURE [B14]
•
Select current limit mode, ILIMIT_MODE [B19]
•
Two current limit configurations are available, STANDARD or
INCREASED
•
Select InnoSwitch3 from drop-down list or enter directly [B20]
•
Select the device from Table 1 according to output power, input
voltage and application
•
InnoSwitch3-CE for CV/CC flyback application
•
InnoSwitch3-EP for CV/CC flyback application with 725 V
MOSFET
•
Enter desired maximum switching frequency at full load, FSWITCH
-
ING_MAX [B34]
•
Enter desired reflected output voltage, VOR [B35]
•
Enter core type (if desired), CORE [B63] from drop down menu
•
Suggested core size will be selected automatically if none is
entered [B63]
•
For custom core, enter CORE CODE [B64], and core parameters
from [B65] to [B72]
•
Enter secondary number of turns [B88]
If any warnings are generated, make changes to the design by
following instructions in spreadsheet column D.
•
Build transformer as suggested in “Transformer Construction” tab
•
Select key components
•
Build prototype and iterate design as necessary, entering measured
values into spreadsheet where estimates were used (e.g. efficiency,
V
MIN
). Note that the initial efficiency estimate is very conservative.

1. Minimum continuous power in a typical non-ventilated enclosed typical size
adapter measured at 40 °C ambient. Max output power is dependent on the
design. With condition that package temperature must be < 125 °C.
2. Minimum peak power capability.
