DLPA3000 VLED current

Other Parts Discussed in Thread: DLPC3438, DLP3010, DLPA3000

I designed projector(DLP3010+DLPC3438+DLPA3000) and measured DLPA3000 VLED(ANODE) current as shown below.
LED current parameters are R:700(4.5A)/G:1023(6A)/B:1023(6A).

Why are actual currents different between Green and Blue?

Thanks.

Hello User,
The RED LED is not supporting a current up to 6 A. That is the reason why the firmware is limiting the current for the RED LED to 4.5A.

Please let me know if you have any further questions.

Best regards,

Nadine

Hello Nadine,

Thank you for your information.

I understood Red LED restriction. I would like to raise Green LED up to 6A(Actually maximum 5.6A). Do you have any ideas regarding realization of Green LED 6A?

Thanks and regards,
Uryyy

Hello User,

I would need more information about your system to be able to address your question.

What RLIM value are you using on your design ? What firmware version are you using ?

Best regards,

Nadine
