• ADP8140 Vin range

    Hi

    I have a question about ADP8140 Vin range.

    If VIN is 5V and VOUT is 16V (sink is a few voltage),

    Are there any caution?

    Because some characteristics is over 5.7V (channel ovp),

    Nearest case is Figure 35 (and external 5V input to VIN)

  • ADP8140 3-string operation and sink pin over voltage

    Hi

    I have two question about ADP8140.

    1:

    Can ADP8140  operate under 3-string?

    Under 1-string open circuit(SINKx),

    2:

    Absolute Maximum Ratings about SINKx is 21V(max).

     

    If all LED gets shorted  when using 100V as power line we would see 100V on SINKx…

  • Notes for using Ir-LED with ADP8140 white LED driver

    Dear Sir/Madam,

    Our customer is studying to use Ir-LED driver with your white LED driver like a ADP8140.

    So what is the notes to use as Ir-LED driver?

    Only Vf difference?

    Why are your LED drivers designed for white LED only?

    Thanks Kaos

    Hi jgavin,

    Please take a look at  ADP8140 as it is similar to what you are looking for. Figure 34, and 36 are using buck regulator (ADP2441, ADP2384) paired with this LED driver.
