Product information
Description
Features:1.This product is a current-regulating 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.
2.It consists of a high-precision reference voltage, an amplifier, a current mirror, etc.The on-chip power transistor and current-sensing block significantly reduce the number of external components, making this product ideal for LED drivers.
3.When the CE pin is high, the input voltage is greater than 2.8V and greater than the LED's forward voltage plus the required voltage drop. It then functions normally to provide a constant current from the LED pin.
4.Adopts temperature regulation instead of temperature protection. Temperature regulation can keep the LED continuously lit in case of high ambient temperature or high voltage drop.When the junction temperature reaches approximately 15°C.With an electronic chip activation function, which can shut down the entire chip to limit current consumption to less than 1µA.Specifications:Features:

4.Adopting temperature regulation instead of temperature protection, temperature regulation can keep the LED continuously lit in the event of high ambient temperature or high voltage drop.When the junction temperature reaches approximately 135°C, the internal temperature regulation block reduces the LED current to prevent the junction temperature from rising further.This feature allows users to maximize the chip's power management capacity without worrying about chip overheating and damage to the chip or external components.
5.With the electronic chip activation function, which can shut down the entire chip to limit current consumption to less than 1µA.
6.Adopts overcurrent protection.When the LED current approaches 1.9A (typical), the overcurrent protection block activates to prevent the LED current from increasing further. LED Driver 4.5V 5V 6V
Output Current: 30-1500mA
Maximum Output Power: 9W
Can drive 1 to 16 2.8-6V LEDs (maximum current does not exceed 1.5A)
