AL5809-150P1-7

AL5809-150P1-7 is a 60V two-terminal constant current LED driver. It provides a cost-effective two-pin solution. It has an excellent temperature stability of 20ppm/°C and the current accuracy ±5% regulated over a wide voltage and temperature range. The AL5809 comes in various fixed output current versions removing the need for external current setting resistors creating a simple solution for the linear driving of LEDs. It supports both the high-side and low-side driving of LED chains. The AL5809 turns on when the voltage between IN and OUT swings from 2.5V upto 60V enabling it to drive long LED chains. The floating ground, 60V voltage rating between input and output pin is designed to withstand the high peak voltage incurred in offline applications. It is used in applications such as offline LED lamps, LED power supplies, white goods, LED signs, and instrumentation illumination.
