■ APPLICATION INFORMATION (Continued)
<Separate Supply Source of the Step-up Circuit (V IN ) from V IN Pin>
Supply source of the step-up circuit can be used separately from V IN pin.
Circuit example of separating supply source of
the step-up circuit from V IN pin ( 3 LEDs)
Circuit example of separating supply source of
the step-up circuit from V IN pin ( 2 LEDs)
Note: Please input 2.5V~6V to the V IN pin when you use.
<LED Open-circuit Protection>
If white LEDs are opened or damaged, the FB pin is pulled down, so that the operating duty ratio reaches the maximum.
Accordingly, the output voltage continues to increase, possibly causing the Lx pin voltage to exceed the absolute maximum
rating of 22V.
If white LEDs are opened or damaged, the detector built in the Lx pin causes the IC to stop oscillating, preventing excessive
increase of the output voltage. However, the detector may detect an overvoltage if the Lx pin voltage exceeds 18V, which is
the overvoltage limit, even when no LEDs are open. Therefore, care must be taken if four LEDs each having a forward
voltage of 4.45V or more are connected in series.
<Startup Inrush Current>
The XC9133 series has no soft-start circuit built-in in order to minimize delay at startup. The inrush current can reach up
to the current limit I LIM .
In some cases, overshoot can occur.
