LM3414HV: The minimum LED current ?

David Yang

Part Number: LM3414HV
Other Parts Discussed in Thread: LM3414, TPS922050

Tool/software:

Hi,

In the datasheet, it is mentioned that the LED current is 350mA to 1000mA.But in the Analog Dimming Control, it is mentioned that the minimum LED current is 100mA.

Because the customer has other projects with LED currents up to 120mA, the RnD is asking what the minimum LED current of LM3414 can be?

Thanks & best regards,

Hi David,

As you can see from datasheet 8.1.2, the LED current can be set to any level in the range from 350mA to 1A with providing accurate LED current. If you need 120mA LED current, I would recommend you can try TPS922050 which could be a good fit here.

Thank you!
