Hi SF, 1. If you do the math and use figure 13 in the user guide, you may be able to achieve 15Hz. The instantaneous current is 3.3uF*(150/(1/Freq)). The plot at 150V shows an instantaneous current of ~7mA. This is about 14Hz. 2. No, you can reference figure 26 of the DRV2700 datasheet and the thermal values listed in the spec table. 3. This is not possible. The DRV2700 architecture requires VDD = SW and the operating range is only up to 5.5V.
