LM3409: Please recommend a driver ic to controll high power UV-LED light source(0~1A) precisely.

Part Number: LM3409

Tool/software:

Dear Texas Instruments,

I'm Sooyang Lee, and I'm a science researcher at Jooam Corp.

I'm looking for driver ic which drive an high power UV-LED light source.

We have to controll a current through our UV-LED light source in range of 0 ~ 1A  precisely.

We are going to connect LED driver ic into Arduino board with DAC.

We entered a purpose current value to our GUI, and then GUI communicate with Arduino firmware.

In that case, what kind of driver ic should we use?

Please, recommend the drive ic and a proper connection method.

Thank you.

Best regards,

Sooyang Lee

    May I know

    1. what is input and output voltage range? 

    2. What is target output current accuracy? 

    You may consider TPS92643, which has higher accuracy performance with average current mode control device comparing to LM3409 which uses peak current control mode.
