Wide Analog control voltage extends LED lamp dimming range in Diodes' low EMI buck high brightness LED driver

The AL8807A is an enhancement of Diodes’ low EMI buck high brightness LED driver AL8807. It extends the analog dimming range in excess of 10:1.

The AL8807A provides protection against a number of potential faults within a lamp:

1. Over-temperature condition - Switches itself off

2. Open-LEDs - Automatically stops switching

3. Short-LEDs - Continues switching but at reduced duty cycle minimizing power dissipation

The AL8807A can operate at up to 1MHz – reducing the size of external components. The small MSOP-8EP package size (same footprint as AL8806/7) coupled with the need for only 4 external components produces a small solution footprint.

The accuracy, temperature range, cost and analog dimming range make it ideally suited to dimmable LED lighting applications.
