CSD96415: Current sharing in Drmos

Jayden Qiu

Part Number: CSD96415
Other Parts Discussed in Thread: CSD95430

Hi Team,

This is Jayden, FAE for ZTE. Does our multiphase Drmos solution support phase expansion?

If so, how to deal with the current sharing problem? Is there any relevant technical documentation that introduces active current sharing measures?

Thanks

Hello,

What do you mean by phase expansion? does it mean driving multi-phase by single PWM? CSD96415 does not support this feature but CSD95430 does. CSD95430 power stage features an active current balance feature which allows multiple power stages to be paralleled off a single PWM input.

Regards

Yes, you're right. Do we have relevant technical documentation which introduces active current balance feature that can be shared with customer?

Thanks.
