DRV8210P: Driving a transformer

Antenna_Head

Part Number: DRV8210P
Other Parts Discussed in Thread: DRV8848

On behalf of a customer.

Considering using the DRV8210P to drive a transformer at 100 kHz for a small isolated power supply, driving with 50% duty cycle PWM. The very small size and low cost of this device is compelling.

Any concerns with doing something like this?

Thanks!

Steve,

Please see this app note. It is written for the DRV8848, but same design guidelines should apply to DRV8210P.

Thanks, this is pretty useful. Would suggest adding to literature list of all of the fully integrated brush motor drivers that it could apply to. Also, might be good to have this in the applications section of the data sheet.

Thanks, -Steve
