400V Linear Regulators from Diodes Incorporated Deliver Constant LED Current in Compact Packages

PLANO, Texas — (BUSINESS WIRE) — May 10, 2018 — Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic, analog and mixed-signal semiconductor markets, today announced the AL5890. This 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 BoM cost and sizes are important. The fully integrated design includes a power transistor and it is available in 10mA, 15mA, 20mA, 30mA, and 40mA 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 ±2.0mA (typ), working over a wide ambient temperature range of -40°C to +105°C.

Its simple two-pin PowerDI®123 design means it can be inserted directly in the LED string in low-side AC or DC, or high-side AC or DC linear configurations without any external resistors. It is designed to tolerate DC voltages of up to 400V and can be used in off-line applications up to 230VAC. Thermal foldback protection is included, which prevents system failure by reducing the current in the event of high operating temperatures. As well as lowering the overall BoM, it also provides an effective solution to tackling EMI without the need for additional switching inductors.

Packaging options include PowerDI®123, SOT89-3L, and TO252-3L to help address heat dissipation in various LED lighting applications including LED lamps, commercial LED fixtures, emergency lighting, signage and downlights, as well as decorative and architectural lighting.
