Hi team,

Now my customer has a p2p flyback controller recommendation requirement, which he want to P2P replace the OB2532 with 24W output power.
By the way, the price should be as low as possible.
Do you have any recommendation?

Best Regards

Hi Wesley,

Our closest comparison for SOT23-6 package would be UCC28742 but please note it is not pin to pin compatible with the OB2532MP.

Hi Ben,

Thanks for your recommendation.

1. But customer use the OB2532 as the flyback controller with primary side feedback mode, as I know, the UCC28742 can't apply the primary side feedback mode.

2. Do you have other recommendation of Flyback controller which have the primary side feedback mode with SOT-23-6 and low cost?

Best Regards

Hi Wesley,

UCC28704 is a primary side regulated controller in SOT23-6 package.
