DC-DC Converter From Diodes Incorporated Saves Space In LED Lighting Applications

Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today announced a miniature DC-DC converter supporting boost, buck and voltage-inverting circuit topologies for LED lighting and general-purpose power management applications. The AL8811 is available in the 3.0mm x 4.9mm x 1.1mm MSOP-8L package, requiring minimal external components and enabling significant reductions in both circuit footprint and BOM cost.

While the AL8811 is advantageous for many low-voltage LED lighting applications, dimmable MR16 lamps will particularly benefit from the new device. For example, using the AL8811 in boost mode in conjunction with an AL8807A buck LED driver creates a high-power factor, dimmable MR16 solution that is both compact in size and low in component cost. Additionally, this two-stage design ensures good compatibility with a variety of electronic transformers and low LED current ripple.

With a wide 3V to 20V input voltage operating range and an output voltage up to 36V, the AL8811 is suitable for an array of different 12V AC lighting applications. The device’s shut-down current is also very low at 0.01µA (typical), while its maximum output switch current is 1.6A.

Comprising an internal temperature-compensated reference, a controlled duty cycle oscillator with an active current-limit circuit, driver and high-current output switch, the AL8811 from Diodes Incorporated provides designers with a particularly versatile solution for DC-DC conversion circuits.
