Details:

SLM503A
 
24V, 15mA -150mA three channel linear constant current LED driver chip
The SLM503A series products are LED driver chips used to generate single channel, high-precision constant current sources, which are very simple to use in various LED lighting products. SLM503A 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. The VDD pin of SLM503A can serve as an output enable (OE) function, and when combined with a digital PWM control circuit, it can achieve more precise dimming applications. In addition, the precise over temperature protection function and anti-static protection design of SLM503A can ensure the safety of the entire lighting system in design, installation, and application.
15mA-60mA current output, 8-speed constant current option, no need for external resistance to set current
Wide input voltage range: 3V to 24V
Power conversion efficiency up to 98%
Ultra low drop out voltage drop (as low as 400mV when driven by 20mA)
± 5% accuracy of output current
Power and load regulation rate 0.1%/V
Chip operating temperature -40 ℃ to 125 ℃
Equipped with chip over temperature protection function and linear current limiting
