TPS92691: Characteristic chart of analog control

Part Number: TPS92691

Hi,

I am considering using the LED driver with the following specifications.
I believe that TPS92691 is applicable.
However, if you look at the diagram of the analog control of the data sheet, there is no entry up to 100mA.
Is it possible to analog control up to 20mA?


(specification)
VIN : 12V or 24V
VOUT : 6.4V(VF)×5, series connection
LED current : 20mA to 100mA
Both analog control and PWM control are required
Period of PWM control and DUTY are undecided

Best regards,

  • Hello,

    Yes, you can make the range 20mA to 100mA. You just need to change the current sense resistor value. Of course you can also use smaller components in the end application if the maximum current is only 100mA instead of 1.5A as shown in the graph.

    Regards,
