Part Number:TPS61196
Dear Sirs or Madams,
Please let me have following questions;
Q1.
Can we use TPS61196 under the condition that LED current ILED is set to be less than 50mA?
If the answer is "NO" or "Not Recommended", please let me know what kinds of negative phenomenon occur
when the IC is used with "ILED < 50mA".
The IC doesn't sink LED current at all? Or, the accuracy of LED current setting becomes much worse than 1.5%?
Q2.
If we can NOT use TPS61196 with "ILED < 50mA", please let me know what IC should be used
on the lower LED current like 30mA or 40mA per one LED string.
We now plan to make the electrical circuit to control the LCD panel whose characteristics are as follows;
-The LDC panel has two connectors to which 4 LED strings are connected respectively.
-LED current is 30mA-40mA per one string.
-The required anode voltage to LED strings is about 70V at maximum.
Best regards,
Shinsuke Tanaka
