■APPLICATION INFORMATION (Continued)
<Separate Supply Source of the Step-up Circuit (V
<Illumination of Six in Total White LEDs>
<Use as Flash>
Supply source of the step-up circuit can be used separately from V
VIN
Note: Please input 2.5V~6V to the V
It is possible to illuminate three-series two parallel white LEDs, six in total, using an input voltage V
1.7V~
An LED current 65mA (MAX.) can be supplied to two white LEDs.
