ONNECTIONS
Hints: For best results, use only one of the three possible LED dimming methods at a time. LED current can be monitored
by measuring the voltage from LED4 cathode to GND and dividing by 15 (the value of R4).
NOTE: Jumper JU1 must be connected for the LX1995 to function. This jumper can be replaced with a wire loop so the
inductor current waveform can be observed using a current probe.
