LM3414: Part maximum duty cycle

Part Number: LM3414


Are you able to provide a maximum duty cycle value for your LM3414 buck LED driver? Or can Vin = Vout?

Many thanks,.

Best regards,

  • Hi Josh,

        Since the LM3414 works under constant on time mode, the on time depends on the working condition related to the Vin/Vout/Iout. We don't have the maximum duty cycle for the LM3414, but we have the spec of the minimum off time which is less than 400ns. The maximum duty cycle depends on the real application and condition.
