APPLICATIO S I FOR ATIO
Board Layout
The high voltage operation of the the LT3750 demands
careful attention to board layout. Observe the following
points:
1. Minimize the area of the high voltage end of the second-
2. Provide sufficient spacing for all high voltage nodes
ary winding.
(NMOS drain, V
transformer) in order to meet breakdown voltage
requirements.

3. Keep the electrical path formed by C1, the primary of T1
M1
and drain of the NMOS as small as possible. Increasing
the size of this path effectively increases the leakage
inductance of T1 resulting in an overvoltage condition
on the drain of the NMOS.
