This is the positive connection for power supply. The leads to the input supply should be twisted and kept as short
as possible.
This is the return connection for the power supply
Ground clip
CTRL / Enable
This jumper should be used to demonstrate PWM dimming of the LED string. In that case jumper J5 MUST be left
open for proper operation.
When a digital signal with a high state logic level of 1.2 V or greater is applied this will enable the boost converter.
By varying the duty cycle of this signal, the average LED current can be reduced thus dimming the LEDs. The
frequency of this signal should be between 100 and 1000 Hertz.
CTRL / Enable:
To enable the boost converter connect a shorting jumper between J5−1 and J5−2
LEDs Selection:
This header allows the user to select the number of LEDs in the string to be driven by the boost converter.
Connect the shorting jumper between J4−7−8 to drive 2 LEDs
Connect the shorting jumper between J4−5−6 to drive 3 LEDs
Connect the shorting jumper between J4−3−4 to drive 4 LEDs
Connect the shorting jumper between J4−1−2 to drive 5 LEDs
If no jumper is inserted in J4, then the driver will operate in the OVP (Over Voltage Protection) mode.
Current Selection:
This jumper allows to select two different output current:
Shorting jumper between J6−1 and J6−2 give a fixed output current determining by R1.
Shorting jumper between J6−2 and J6−3 R3 allow adjusting the output current via potentiometer R3.
