Description

JW1882 is a dual-channel linear LED driver that integrates 500V MOSFET and JFET high-voltage power supply functions. The output peak current is set by the external sampling resistance. JW1882 switches the on-off state of two constant current outputs by turning on and off the power switch according to the FN pin settings, and achieves the dimming effect through different peripheral RS resistance connection methods. JW1882 has a built-in over-temperature protection function. When the chip junction temperature exceeds the over-temperature protection threshold, the chip reduces the output current to reduce the chip temperature. Product features Minimalist peripheral circuit Success rate control 3 kinds of color temperature sequence switching 3 kinds of brightness sequence switching 150oC OTP protection Product diagram
