APPLICATION NOTES
1.
Recommended circuit
This series has been tested according to the following recommended testing circuit before leaving the factory. This series should be
tested under load (see Figure 2). If you want to further decrease the input/output ripple, you can increase the capacitance accordingly
or choose capacitors with low ESR. However, the capacitance of the output
fi
lter capacitor must be appropriate. If the capacitance is
too high, a startup problem might arise. For every channel of the output, to ensure safe and reliable operation, the maximum capaci-
tance must be less than the maximum capacitive load (see table 1).

Note:
1. Minimum load shouldn't be less than 5%, otherwise ripple may increase dramatically. Operation under minimum load will not damage the converter, however, they may
not meet all specifications listed.
2. Maximum capacitive load is tested at input voltage range and full load.
3. All specifications are measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
The voltage applied to IRF3205 is VDS = 5V, VGS = 4V. According to the manual, when VGS = 4V, the current is less than 10A, which is much smaller than the drain continuous current of 110A mentioned in...
