UCC256303: OCP2 threshold

Kazuki Itoh

Part Number: UCC256303
Other Parts Discussed in Thread: UCC256403

Hi team,

In the datasheet, OCP2 threshold range for UCC256303 is defined as ~0.84V +/-19%.
This tolerance looks large.
My customer would like to set more tight and realistic OCP2 target.
So, could you kindly provide the OCP2 threshold variation data if possible?

Regards,

Hi Adam-san,

My customer do recognize UCC256403, and trying to migrate from UCC256303.

But due to some exisiting design close to production and UCC256403 availability, some designs need to keep UCC256303.

Can you please answer my question about UCC256303?

Regards,

Itoh
