## Overview

The Adjustable Current LED Driver is a cutting-edge module designed for LED applications, offering a constant output current adjustable from 30mA to 1.5A. With a versatile input voltage range of 2.8V to 6V, it features advanced temperature regulation and built-in safety mechanisms, making it an ideal choice for professionals seeking reliability and efficiency in their LED projects.

## Description

Adjustable Current LED Driver, DC 3.3V 3.7V 5V LED Driver 30-1500mA Constant Current Adjustable Module for LED Li-ion

## Features

- 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 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 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 block. When LED current approaches 1.9A(Typical), the over current block begins to function to prevent the LED current from increasing further.

## Questions & Answers

**Q: Does this use pwn by itself or do you need to supply a pwn signal?**
A: You need to supply a pwm signal, regulated current through adjustable resistor or PWM signal control

**Q: Does it need to be mounted on a heatsink? If so, how?**
A: No need to install on the radiator
The LED Constant Current Adjustable Module 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.

**Q: Can this board drive a 2.7v led at 350ma from a 5v input?**
A: No.  Minimum input is minimum output

**Q: What would be the advantage or disadvantage of using this board vs a single resistor when driving a single 3.6v while led from a 5v wall PS.**
A: For a single LED, there's no advantage. With a regulated DC supply driving a single LED all you'd need is the appropriate value current limiter resistor for your LED.
