UCC28180: Three-phase interleaved PWM controller

Francis Jiang

Part Number: UCC28180
Other Parts Discussed in Thread: UCC28070,

Hi Team,

Customer asks for a three-phase interleaved PWM controller, previously, he used our UCC28070.

I heard that UCC28180 can achieve this function but I don't find the Sync Pin of this device. Could you please help me check it and how to achieve it? Thanks a lot.

BRs,

Francis

Hi Francis,

Thank you for the query.

There is no reference design using both UCC28070 and UCC28180.

The following e2e thread shows how it is done with UCC28070

Hi Harish,

This is a high cost solution, do we have 3-phase device in development?

Hi Francis,

True this is not cost effective, most customers use C2000 for this application.

Thank you

Hi Harish,

Got it, actually, they use C2000 to achieve larger Laser Power, and just ask for whether we have such analog IC solution. No problem here. Thanks.
