Part Number: LM3410

Hello team,

I want to use LM3410 as boost configuration.

I not very familiar to boost converters, but are there any chance LM4310 to be unstable when used at light or no load condition?

Best Regards,
Kei Kuwahara

    Kei, 

    LM3410 is constant current controller and need to charge FB to regulated voltage. If light or no load condition, then there is definitely something wrong and output voltage will keep rising as FB is low. You need to add overvoltage protection circuit to avoid potential risk. Please refer to 8.1.1.7 Output Overvoltage Protection for details.
