Hi all,
I have designed a BPA200 amplifier board using two LM4780s per channel (+-200W RMS Output), and I am seeking some tips for it's design.
The schematic is just a copy of the AN-1192 application note's, with servos. I have removed the paralleling resistors, leaving 4 different outputs that will be joint in a separate board (for thicker gauge wiring and convenience).
This is the board (no mounting holes at the moment):
Top Ground Plane (ratnest) hidden (unrouted connections are routed via the top layer groundplane):
Ground Plane (ratnest) Hidden:
This is the schematic of the board that will join the signals (just 5w resistors):
Have you got any tips? It passes EAGLE Cad's ERC, and the board and schematic design are consistent. Thanks in advance,
Gonzalo Ruiz.
