LM3414: LM3414 analog dimming mode

Ray Vincent Aranzaso

Part Number: LM3414

Hi,

Good Day. Our customer is using LM3414 integrated circuit in analog dimming mode and he like to control the current from 500mA to 30mA. Are there any problems using this integrated circuit with this minimum current (30mA)? Thank you very much.

Best Regards,

Hi Ray,

The output current amplitude can be set through IADJ and the IOUT is configured by input PWM signal(DIM pin). It's bot recommended to set the output current amplitude lower than 350mA.
