CN5711 LED Driver Module DC 3.3/3.7/5V LED Driver 30-1500mA Constant Current Adjustable

CN5711 LED Driver Module - Product Page Description (English)

Overview:

The CN5711 is a constant current modulation integrated circuit capable of delivering an output current of up to 1.5A, designed to drive various types of LEDs, including white LEDs. The LED current is set by an external resistor, adjustable from 30mA to 1.5A. An integrated power transistor minimizes the need for external components. Additional features include die temperature modulation and a chip enable input.

The CN5711 requires few external components, is easy to use, supports multiple dimming modes, and offers high efficiency, making it ideal for portable applications.

Key Features:
