Alfa-MOS Technology AF1880 500V / 50mA Linear LED Driver General Description The AF1880 is a linear LED driver. The application of high bright LED is widely used for general illumination. The AF1880 maximum output current is 50mA. Typical variations is ̈́˅% in VIN = 6 ~ 500V input voltage range and -40 ~ 85ʳ кʳ temperature range. Ground current is approximately 32µA, from zero to maximum loading conditions at TA=25к. Built-in thermal shutdown protection against any fault conditions. The output current can be setting by place a resistor at VCS pin. For ease of application, the AF1880 comes in the popular 3-pin SOT-223. Features 6~500V wide input voltage range. Least external component. Typical ground current is 32µA.ʳ ̈́2% accuracy VCS voltage.
