  Mains-Dimmable LED Lamp Driver from Diodes Incorporated Raises Device
  Flexibility while Reducing BOM Cost

Business Wire

PLANO, Texas -- December 19, 2013

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 AP1694,
an AC-DC controller providing a universal high-performance driver solution for
a variety of mains-dimmable LED lamp designs. Suitable for both 120V and 230V
AC inputs, while supporting non-isolated buck, buck-boost and isolated flyback
topologies, this part enables between 10% and 50% reductions in total BOM
costs.

The controller uses Diodes’ patented PFM technology to tightly regulate LED
current and achieve a high power factor and low total harmonic distortion. By
operating in boundary-conduction mode, the AP1684 also assures high efficiency
and low EMI driver characteristics. As a primary side controller, this part
removes the need for opto-coupler and secondary-side control circuitry, and
being inherently stable, eliminates the need for loop compensation.

The AP1694 delivers a 5% initial LED current accuracy, meeting the
requirements of most mains-dimmable LED lighting applications and is
compatible with a wide range of different dimmers, including both leading edge
and trailing edge types. It achieves deep dimming down to 1%, complies with
the NEMA SSL6 standard for dimming curves and meets the requirements of the
IEC6100-3-2 harmonic standard.

Provided in the small form factor SO-8 package and requiring only 26 external
components in buck topology, the AP1694 driver controller offers designers of
mains-dimmable LED lamps a higher power density with a simpler and smaller
total circuit footprint. The device also integrates comprehensive protection
features, including open-load detection, over-voltage, short-circuit and
over-temperature protection. For further information, visit the Company’s
