PC Board Layout Checklist
When laying out the printed circuit board, the following
checklist should be used to ensure proper operation of
the LTC3900 for your layout:
1. Connect the 4.7μF bypass capacitor as close as possible
to the V

is used.
2. Connect the two MOSFET drain terminals directly to
the transformer. The two MOSFET sources should be as
close together as possible.
3. Keep the timer, SYNC and V
from the high current path of Q3, Q4 and T1.
4. Place the timer capacitor, C
to the LTC3900.
5. Keep the PCB trace from the resistors R
