Dear support team,

May I know the LM3697 support individually-adjustable brightness control for the each channel(HVLED1/2/3)?

If Yes, may I learn from you how to do the brightness control?

If No, do you have suggest solution for such kind requirement?

Best Regards,

Gary Chen

Hi Gary,

The LM3697 has two brightness controls which can be used to control two HVLEDxx groups. One group can be two HVLEDxx with the other group containing one HVLEDxx. There is not any method to control all three HVLEDxx independently. Let me know if you need any additional information.

Best regards,
Randy

Hi Gary,

The LM3532 is probably the best option for your application. Another possible option is the TPS61196.
