Other Parts Discussed in Thread: TPS3802
Tool/software:
Dears,
Application scenarios:
Switching power supply, voltage 30V, using 2pcs TPA3221, all in main mode, 600KHZ, TBTL mode. Switching power supply outputs 28.5V to power amplifier;
Customer proposes several improvement plans，
1. The voltage of the switch power supply is too high. The customer has already modified the parameters and fully checked the voltage with the power supplier.
2. Reset circuit logic issue. There is currently no reset circuit connected, it is due to the resistor being pulled high. Do we need to separate two TPS3802 according to the EVM board?
3. Do I need to set master-slave when two amplifier chips are on the same board?
4. Is the input signal too large? Plan to modify the input circuit limit.
Based on the above, please help check the circuit and provide optimization suggestions.
