AL5890-20D-13

Diodes' AL5890 has temperature stability and the current accuracy of < ±2.0 mA (typical) regulated over a wide voltage and temperature range. The AL5890 comes in various fixed output current options removing the need for external current setting resistors and creating a simple driver solution for the series of LEDs. The AL5890 supports both the high-side and low-side driving of LED chains. The AL5890 turns on when the voltage between IN and OUT is greater than 7 V. Long LED chain application up to 400 V operating voltage subject to package thermal limitation. The AL5890 has thermal foldback protection, and this enhances the safety of the system at high temperatures. It is available in thermally robust PowerDI® 123 (Type B), SOT89-3L, and TO252-3L packages.<strong>Features:</strong> Integrated power transistor with output current up to 40 mA Small form factor to minimize design space and save cost, 400 V operating voltage Supports both 120 VAC and 230 VAC system, Available in PowerDI 123, SOT89, and TO252 package Available in compact and thermal packages for size-constrained applications, LED current tolerance over wide temperature range < ±2.0 mA (typ.) Good LED current accuracy 5% at 40 mA, Thermal fold-back protection Automatically reduces LED current to prevent system overheating, Commercial LED lighting fixtures, Emergency lighting, Signage, downlights, decorative, and architectural lighting
