Dimmable Buck LED Driver from Diodes Incorporated Simplifies LED Lighting Design

PLANO, Texas — (BUSINESS WIRE) — March 13, 2014 — 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 introduced the AL8807B dimmable buck LED driver. The AL8807B enables a reduction in component count and PCB size in 12V and 24V LED lighting systems and MR16-type LED lamps. This is a hysteretic driver with an integrated power switch and operates at a switching frequency of 1MHz.

The output current is set using a single external sense resistor and dimming is achieved by applying a fast digital PWM signal to the driver’s control input. A low voltage, applied to the same input, turns the output power switch off. Lamp reliability is ensured by the driver’s built-in, over-temperature, LED open-circuit and short-circuit protection features.

By packaging the driver in a small footprint, low thermal-resistance MSOP-8EP package, a higher power density is achieved, maximizing the permissible LED current over a wider ambient temperature range. The AL8807B delivers an LED drive current up to 1.3A and operates between -40ºC to +125ºC with an efficiency of 96%.

From voltage sources between 6V and 36V, the driver will produce a constant current for a chain of high-brightness LEDs. Average LED current accuracy is better than 5%, helping to improve channel-to-channel matching and while meeting the requirements of most medium-voltage LED lighting products.
