Tool/software:

Hello There,

I have an application where I’ll need to power different UV LED strings. Below are the specification requirements. Could you help me with suggestions for LED drivers and circuits? Any suggestions are welcome.

Spec: Voltage OutPut 96V~192V; Current 0.005A~0.050A; (with higher VF typically lower IF), Control LED intensity.

Thanks.

Hi Rene,

Sorry for the late response.

May I understand what is your input voltage? Do you need to build a circuit to accommodate all output voltage range of 96V - 192V and output current range of 0.005A - 0.050A? What dimming mode do you need, analog dimming or PWM dimming or others?

Best Regards,

Steven

Hi Steven,

Yes, I need the output voltage range to be 96-192V, with the current range between 0.005A and 0.05A. Analog dimming is preferable for us since this is an analog application, and any noise reduction would be beneficial. The input voltage is 19V DC.

Thanks for your reply.

Best Regards.
Rene
