DESCRIPTION

Switch Output. SW is the drain of the internal N-Ch MOSFET switch.

Signal and power ground. Connect directly to ground plane.

Logic level dimming input. Drive DIM low to turn off the current regulator.

Drive DIM high to enable the current regulator.

Current sense input

Input Supply Pin. Must be locally bypassed.

Internally connected to GND. Mount on board for lower thermal resistance.

No connection
