Hi All,
We're designing a power output stage with the TAS5613. We've built a prototype board basing on the schematics of the TAS5613 evaluation board but i cannot find the toroidal inductor (toko C3B-A0336). We tried replacing with http://docs-europe.electrocomponents.com/webdocs/002b/0900766b8002b270.pdf this choke, but it did'nt worked.
We're trying to use the chip in BTL configuration (M1 M2 M3 = 0 1 0) but at the outputs A and B (without any LC filter) i can read the same PWM signal and not two opposite-phase signals as expected. Even with the correct LC filter at the output we won't be able to get any signal, cause the two filtered PWM waves will mix in-phase producing no output.
Is there any configuration we're missing or should we use mutual coupled inductors to change the phase of one wave? We thought of this last option just because of the symbol used in the evalutation board schematics.
Can you please suggest any troubleshooting procedure to solve filter-related issues?
Thanks in advance for your help,
Best regards
