About this item

  • This product 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.
  • It 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 this product 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, it functions normally to deliver constant current from the LED pin.
  • 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 junction temperature reaches about 1
  • With e chip enable function, which can shutdown the whole chip to limit the current consumption within 1uA. 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.

Stand Alone Adjustable Small Led strip Driver
4 Stars
Stand Alone Adjustable Small Led strip Driver
This Adjustable Led driver worked for my needs. I used this Led driver on a short 4" piece of 5v 4000k Cob led strip. I mounted the strip on the back side of my TG-16 logo after cutting out a window on the plastic console case, that turns on with power switch for power on indicator. I used the source power of 5v 1 amp off of a 5v regulator on my Turbografx-16. Connections - V1 5v in & with a jumper wire to CE, G Ground in from source and shared Led ground wire, Led for positive Led. Be very careful when adjusting the current adjustment screw. It does not fully rotate all the way around. It has less than 300° of back and fourth rotation. If you over rotate it it will break and you will loose adjustability, I found out the hard way. It works well and dims and brightens my small led strip for my TG-16 power logo light. Draws approximately 300MA. Worth it for my needs. Temporary mounting in progress, & Will clean up nice when finished. Recommend for small led projects and very small footprint for limited space just be careful with adjustment screw.

I am a beginner when it comes to electronic circuits but I greatly enjoy learning about making different projects. This LED adjustable driver works perfectly for whatever your project may be. It was fairly simple to figure out. I used it with an Arduino UNO which worked perfectly in my project. The only confusing part was how the description says 3.3V/3.7V or 5V but the instructions on down the page say input is 2.8-6V. Still very easy to use.

2.0 out of 5 stars Caveat - Resistance adjustment and CE PWM frequency
Reviewed in the United States on October 23, 2023
Verified Purchase
This star rating is not about the functioning of the product but about the quality of the documentation.

I tried to control an IR LED with this board. To do this, I wanted to use the adjustable resistance to set the current and the CE through PWM to control the pulse.
The good:
The pad placement on the PCB is the correct pitch for stake pins, so I was able to solder a header and attach wires into them

The bad:
The "adjustment" has to be made with a flat screw driver of blade size that is very specific. The blade edge has to be under 0.8 mm thick and the blade width must be within a certain size tolerance to be able to grip this head. It would be helpful if this specification is posted. Note that a smaller blade width will just rotate inside the circular cavity and a larger blade width will not get into the slot. A Phillips head will not work because there is no depth for the tip.

There is a frequency limit on the PWM of < 2KHz. IR pulse rate is just about this frequency but I was unable to get any output from the LED (which I have driven with a different circuit and the same input). I suspect that this driver is not fast enough for this particular function.

So, I am unable to verify the functionality of the device outside my own requirements. It may work just fine for other needs.
