DLPA3005: Two LED Drive

Part Number: DLPA3005
Other Parts Discussed in Thread: DLPC3439, DLP4710, DLPC3479

Hi，

We use DLPA3005 and DLPC3439 In our previous system. Out system has only one blue channal supporting one LED drive( VF=3.6V). It works fine. Now we want to use two LED in series(VF=7.35V), it does not works. When I enable the LED output, the DLPA3005 would detect some fault and kill the voltage supply to protect itself. So how do I adjust the output voltage(VLED) window to support two LED in series?

Thanks.

Hello Wang,

DLPC3439 chipset is mainly intended for Display projection type of applications and does not support Single Illumination mode. We would request you to switch to DLPC3479 chipset for Light Control Applications.

Regards,

Mayank
