LM3435: About the reason for specifying ILED max

Junya Kato

Part Number: LM3435

Hello Team,

What is the reason for specifying ILED max with "HIGH CURRENT REGULATORS" on page 10 of the datasheet?
I would like to know why it is specifying the lower limit of ILED max.


Is specified to realize I2C controllable STEP?

Best regards,
Kato

    Hello Kato,

    I'm guessing that the range is the maximum depending on operating conditions and is dependent on thermals. But I will forward this to somebody that knows this device a bit better. Could you clarify exactly what you are asking? I'm sorry, it isn't exactly clear to me. Thanks.

    Regards,

    Clint

    Hi Kato-san,

    The planned application with the device during design stage was requiring 0.5 A to 2.0 A.
    The circuit works in CCM for the proprietary switching control scheme maintain fairly constant switching frequency as well.
    Design team from that time believed that 0.5 A is a reasonable current to keep CCM if the max current to be used in the system goes up to 2.0 A.

    I hope the above answered your question.
