Details:

SLM211A series
 
24V, 15mA-200mA single channel linear constant current LED driver chip
The SLM211A product is an LED driver chip used to generate a single channel, high-precision constant current source, which is very simple and easy to use in various LED lighting products. The SLM211A features a wide input voltage range, high output accuracy, ultra-low drop out voltage drop, and excellent linear/load adjustment rate, ensuring high-quality lighting driving in applications such as online strip lights, luminous characters, and advertising panel backlighting. In most applications, SLM211A only needs to connect a resistor from SET to GND to set the output current. In addition, SLM211A also supports PWM dimming in the frequency range of 100Hz~20kHz, and can achieve a dimming depth of 1024:1 under 100Hz conditions. The over temperature protection function of SLM211A activates the linear current reduction function when the chip junction temperature reaches 135 ℃, thereby reducing system power consumption without causing LED flicker. The anti-static protection design of SLM211A can ensure the safety of the entire lighting system in design, installation, and application.
