APPLICATIO S I FOR ATIO
A planar transformer PA0191 by Pulse Engineering is
employed as the power transformer in this design. This
transformer is constructed on a PQ20 core with nine turns
of primary windings, two turns of secondary windings and
seven turns of auxiliary windings for the LT3781 bias
supply. Si7892DP MOSFETs are selected for the second-
ary side due to their low R DS (ON) , 30V V DSS rating and
The switching frequency of the circuit is about 230kHz.
1500V input to output isolation is provided. Additional
features of this design include primary side on/off control,
input over voltage protection, under voltage lockout, soft
start and board over temperature shutdown. The complete
design is mounted within a standard half brick PC board
with about half inch height.
compact, thermally enhanced PowerPak SO-8 package.
