40V Step-Up Converter for 4 to 10 White LEDs

Pin Descriptions

Pin # Symbol Function

PVIN

EN/SET

Input power pin; connected to the source of the P-channel MOSFET. Connect to the input capacitor(s).

IC enable pin and S²Cwire input control to set output current.

FB voltage range select. A logic LOW sets the FB voltage range from 0.4V to 0.1V; a logic HIGH sets the

FB voltage range from 0.6V to 0.3V.

SEL

VIN

N/C

Input voltage for the converter. Connect directly to the PVIN pin.

No connection.

6, 7

Boost converter switching node. Connect the power inductor between this pin and LIN.

Power ground for the boost converter.

Ground pin.

Feedback pin. Connect a resistor to ground to set the maximum LED current.

Feedback pin for over-voltage protection sense.

Switched power input. Connect the power inductor between this pin and SW.
