Product Name : 30-1500MA Adjustable Constant Current LED Driver DC 3.3V 3.7V 4.2V 5V PWM Control Board Buck Power module
Packing list:
1 PCS 30-1500MA LED Driver Module(with Pin and no Pin optional)
Description:
Working voltage : DC 2.8-6V(Perfect for 3V 3.3V 3.7V 5V 6V LED Driver)
Output Current: 30-1500MA
Maximum output power: 9W
Can drive 1-16pcs 3-6V LEDs (maximum current does not exceed 1.5A)
Current regulation: 1 through adjustable resistance; 2 through PWM control
Chip Temperature Regulation
Over LED Current Protection
Operating Temperature Range
Size : 18mm x 10.3mm x 2.8mm
Weight : with Pin 0.86g,no Pin 0.56g
Application 1: Wiring in accordance with the following figure, use a suitable screwdriver gently and slowly rotate the adjustable resistance.
Application 2: Adjust the adjustable resistance to 0 ohms (or maximize the current according to Application 1) and then use the MCU output PWM signal to control the LED output current
the frequency of the PWM signal should be less than 2KHz
LD06AJSA/B is a current regulation integrated circuit operating from an input voltage of 2.8V to 6V, the constant
output current can be set up to 1.5A with an external resistor. The LD06AJSA/B consists of high precision reference
voltage, amplifier, current mirror, etc. The on-chip power transistor and current sense block greatly reduce the
external component count, which makes the LD06AJSA/B ideal for LED driver.
When the CE pin is high, the input voltage is greater than 2.8V, and is larger than the LED forward voltage plus
the required voltage drop, LD06AJSA/B functions normally to deliver constant current from the LED pin.
The LD06AJSA/B adopts the temperature regulation instead of temperature protection function, the temperature
regulation can make the LED being turned on continuously in case of high ambient temperature or high voltage
drop. When the LD06AJSA/B junction temperature reaches about 135 ° C, the internal temperature regulation block
reduces the LED current so that the junction temperature will not rise any more. This feature allows the users to
maximize the use of the power handling capability of the chip, do not worry about the chip overheating and
damage to the chip or external components.
The LD06AJSA/B also has the chip enable function, which can shutdown the whole chip to limit the current
consumption within 1uA.
The LD06AJSA/B also adopts the over current protection block. When LED current approaches 1.9A(Typical), the
over current protection block begins to function to prevent the LED current from increasing further.

2 On board 8 channels 5V to 3.3V(also 3.3V to 5V) Logic level converter,base Limiting resistor;
3  Arduino Breadboard friendly;
4 PCB size:25* 15mm 
 
Level conversion principle:
Between 5V and 3.3V level plus 470 ohm current limiting resistor, to avoid being burned of 3.3V port.
So, when the LOW side no-load, HIGH side plus 5V level,LOW side test is still at 5V level,vice versa.
This is a normal phenomenon, not the level conversion function does not work.
