DRV2667: What is the difference with Flyback mode and normal mode

Hi,

Good day.

Our customer has this question for DRV2667. Please see below

1. We are wondering what is the difference between DRV2667 and DRV 2700? Which one is better choice for high power application?

2. What is the difference between flyback mode and normal mode? Does DRV2667 have flyback mode? How to design

3.  should pin 1,4connected with out+ and out- if we don't use flyback mode?



Thank you for your help.


Regards,

Cedrick
