Part Number: DLPA3005

Hi,

The pin 26, 27, 31 as attached picture are used to control LED top side.

Our customer want to control the three pin but doesn't find them in datasheet.

Could you please tell me can these three pins be controlled and how to control them?

Thanks

Best regards,

Hi Fengyu,

Can you please provide more information about how and why you want to control these three pins?

I don't think these three pins are able to be controlled directly. The DLPA3005 can select the external MOSFET switches for LEDs through CH_SEL_0 and CH_SEL_1.

Regards,

Lori
