Linear regulator for constant LED current

15 August 2018 Power Electronics / Power Management

Diodes Incorporated’s new AL5890 linear constant-current regulator provides simple and more cost-effective solutions for driving LED strings from an off-line or DC power supply. Available in a range of packages, the small form-factor of the AL5890 makes it ideal for any LED application where a lower bill of materials cost and sizes are important. The fully integrated design includes a power transistor and it is available in 10 mA, 15 mA, 20 mA, 30 mA and 40 mA variants. A single device or multiple devices in parallel can be used to source or sink enough current for long LED strings, with an overall accuracy of less than ±2,0 mA (typical), working over a wide ambient temperature range of -40°C to +105°C.
