A8290 - AiT Semiconductor

A8290 LED DRIVER

The LEADCHIP A8290 is a high-voltage adjustable current source with accurate temperature compensation. The device is designed to provide a constant current source determined by an external sense resistor R .SENSE The current is adjustable from 10mA to 20mA with less than 10% error while input changes from 5V to 90V. With an external resistor (R1 in Figure 1).
