Description

Vin

Supply voltage positive input. Apply a DC voltage of 7V to 30V here.

The input is protected with a fuse and a diode to prevent damage from

reserved power supply and safely disconnect the power in case of

failure.

GND

Supply voltage negative input and ground reference for MOD input.

LEDa

Positive output for LED, connect the anode of the first LED of the

string to this pin.

LEDk

Negative output for LED, connect the cathode of the last LED of the

string to this pin. This pin is not identical to GND!

MOD

PWM input. Pulling this pin high shuts off the output. Feeding a PWM

signal with up to 1kHz can be used to control the brightness of the

connected LEDs. Pulling the pin high permanently puts LW05 in a

standby mode. This can be left unconnected if no brightness control is

required.
