LX1995 EVALUATION HOOK UP
The following is a demonstration scenario that
can be used to evaluate the LX1995:
Directions for hook up (DC dimming mode):
1. Install jumper JU1.
2. Connect a 3.6V typical 1A power source
between VIN and GND terminals.
3. Apply a 1.5V DC signal to the DC_ADJ
terminal. Signal GND can be referenced to GND2
for convenience.
4. Vary the DC signal from 0V to 3V and observe
the LEDs dimming. (Measure LED current from
LED4 cathode to GND2 if desired. I = V / 15.
