TSI 20N Series
Method to decrease noise
Usually TSI 20N series is used adding an input/output capacitor,
and making the most of the converter's performance and to decrease
the noise more, consider the following items when designing the
print board.
1. Use low impedance capacitor which has good high frequency
characteristic.
2. Shorten lead of each capacitor as much as possible, and make it low
lead inductance.
3. Make the wiring loop space small between the (+) and (-) of both input
and output pin side as much as possible. You can decrease the effect
of leakage inductance.
4. Design the print pattern of the main circuit thick and short as much as
possible.
