Input Supply Pin. Must be locally decoupled to GND with > 2.2µF X7R ceramic capacitor –
see applications section for more information.
Exposed pad/TAB connect to GND and thermal mass for enhanced thermal impedance.
Should not be used as electrical ground conduction path.

A PWM signal (low level ≤ 0.4V and high level > 2.6; transition times less than 1us)
allows the output current to be adjusted below the level set by the resistor connected
to SET input pin.
