1. The working voltage of TPA3156D2 is specified under 26V. But we want to use at 28V. Because the charging voltage of 24V battery is 28V.
The charging voltage is designed not to exceed 30V.
Is it OK ?.
2. The attached heatsink of TPA3156D2EVM is OK for 2*70W continuous operation (30 minutes or more).
Since It is not OK, how much is the output power?
