5 светодиодных драйверов с регулируемым током, 30–1500 мА, постоянный ток

5 Pieces Adjustable Current LED Driver PWM Controller Replace for LED 18650

Description:

Constant current adjustable Modules: 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.

Quality: It consists of high reference voltage, amplifier, current mirror, etc. The chip power transistor and current sense block greatly reduce the external component count, which makes this product ideal for LED driver.

Function: When the pin is high, the input voltage is greater than 2.8V, and is larger than led forward voltage the required voltage drop, it functions normally to deliver constant current from led pin.

Temperature Regulation:Adopts the temperature regulation instead of temperature protection function, the temperature regulation can make led being turned on continuously in case of high ambient temperature or high voltage drop.

Protection: Adopts the over current protection block. When LED current approaches 1.9A(Typical), the over current protection block begins to function to prevent led current from increasing further.
