ONNECTIONS
The LX1995 Evaluation Board has 9 test lead
attachment point for applying power and dimming
inputs or for monitoring voltages.
Function
Board Label
Connection
Input Power
VIN
Power supply (3.55V+/- 1.95V).
Power Ground
GND
Common power supply ground.
Enable
/SHDN
Connect to GND to disable LX1995. A <1KHz logic PWM signal
can also be applied.
DC dimming
DC_ADJ
Apply a 0 to 3V DC dimming input
PWM dimming
PWM_ADJ
Apply a >5KHz 3.3V logic PWM signal.
Output Voltage
VOUT
Test point to monitor voltage across all LEDs.
Signal Ground
GND#
Multiple common grounds for probes. etc

Connection Points
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.
