DESCRIPTION
NO.

I
This is the enable pin of the device. Connect this pin to ground forces the device into shutdown mode. Pulling
this pin above 1.4V enables the device. This pin has an internal pull-down resistor.
This is the output of the dc-dc converter.
This is the feedback pin of the device. The feedback pin measures the LED current through the sense
resistor. The feedback voltage is set internally to 500mV.
This pin indicates that the dc-dc converter is ready for high current operation (open drain output).
Control / logic ground.
This is the input voltage pin of the device. Connect directly to the input bypass capacitor.
This pin needs to be tied to the input voltage pin of the device.
This is the switching pin of the converter.
Power ground.
Must be soldered to achieve appropriate power dissipation. Should be connected to PGND.
