Diodes High Power Factor Boost LED Driver Effectively Reduces the Occupied Area of Dimmable MR16 LED

The occupied area of al8812 is 6mm x 4mm, and the height from the plate is only 0.6mm. The converter includes a temperature compensated reference, a comparator, a duty cycle controlled oscillator equipped with an active current limiting circuit, a driver, and a high current output switch.

The input voltage range of al8812 is 3V to 20V, and the output voltage can be adjusted up to 60V. The new device works in a wide power supply voltage range and is suitable for medium voltage LED, 12VAC lighting applications and dimmable MR16 LED lamps.

The off current of this converter is generally less than 0.01 µ a, and the maximum output switching current is 3.6a. It has an accurate reference with a tolerance of 2%, which can provide very accurate voltage and current control.

Diodes company combines al8812 with constant current step-down converter al8807a to bring a two-stage reference design for dimmable MR16 LED lamp, so as to provide good transformer compatibility and low current ripple at a very affordable bill of materials cost.
