Description
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.
Supply voltage negative input and ground reference for MOD input.
Positive output for LED, connect the anode of the first LED of the
string to this pin.
Negative output for LED, connect the cathode of the last LED of the
string to this pin. This pin is not identical to GND!
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.
