Part Number: UCC28051
Other Parts Discussed in Thread: UCC28811

Dear Specialists,

My customer are looking for alternative device due to bad delivery of UCC2811.

UCC28051 has the same pin assignment (although the pin names are different) and same block diagram.

The main difference is the CS pin offset (75 mV or 0mV). The other specs are the same.

Could you please let us know the changes when using UCC28051 for LED Driver instead of UCC28811 application circuit.

I appreciate your great help in advance.

Best regards,

Shinichi

Hello Sinichi,

Thank you for your interest in the UCC28051 and UCC28111.

The UCC28051 can be used in place of UCC28811 without any changes to the design.

The 75mV offset is present in both parts (the wording is a different which may be confusing).

Regards,

Ray
