DESCRIPTION
I
The return path for the I_OUT regulation. Current regulator is connected to this pin, and
it can be disabled to open the current path.
I
Output current programming pins. The resistor connected to the pin programs its
corresponding output current.
I
Mode selection pins. See Table 2 for details.
The input pin to the device. It provides the current to the boost power stage and also
I
powers the device circuit. When V_IN is below the undervoltage lockout threshold, the
device turns off and disables outputs, thus disconnecting the WLEDs from the input.
I
This is the switching node of the device.
O
The output of the constant current supply. It is directly connected to the boost
converter output.
O
The ground of the device. Connect the input and output capacitors very close to this
pin.
—
The thermal pad should be soldered to the analog ground. If possible, use thermal via
to connect to ground plane for ideal power dissipation.
