Hello Shyam,

Welcome back to the E2E forum and thank you for your interest in DLP® technology!

Where do you see the pin configuration in your second screenshot?

Below is the circuit capture from the reference design.

Also, the reference design is an example for reference of DLP4710EVM-LC, you may able to change the design for your application.

Regards,

Lori
