ULC1001-DRV290XEVM: ULC1001-DRV290XEVM, eval question.

Hi~

Customer is under evaluating ULC1001-DRV290XEVM board and got several question as below.,

1. At DRV2901,how to boost output voltage? When see bootstrap, looks charge pump architecture and let me know details. Also can we estimate output amplitude voltage? Is it related to amplitude 0.8puV?

2. Output after LC filter could see sinusoidal wave when input is square wave, can we get filter equation? C, V, Freq? etc...

3. In DRV2901 datasheet, FPWM range is 192~432kHz but EVM has 40-400kHz, which one is right? Also in EVM, no output under 50kHz even though EVM input range, why doesn't work?

4. At EVM GUI,what Freq means at region parameters setting area? Is it resonance freq?

Thanks.
