AL1692-10E
DIMMABLE LED DRIVER
Description
The AL1692-10E is a high performance, high power factor, high
efficiency, and high current precision buck-boost and flyback
dimmable LED driver for triac dimmable LED lamp applications. The
AL1692-10E topology provides an accurate output current over wide
line and load regulation. The wide switching frequency operates at
boundary conduction mode (BCM) to ease EMI/EMC design and
testing to meet the latest regulatory standards.
The AL1692-10E LED driver integrates a 700V/1A high voltage
MOSFET. It can cover both 120Vac and 230Vac triac dimmable
applications with eliminating the external high voltage MOSFET and
Varistor, which will reduce the system BOM cost. The AL1692-10E
has the built-in thermal fold-back protection trigger point to
automatically reduce output current. Other protection features
enhance LED lighting system's safety and reliability.
The AL1692-10E dimming curve is compliant with the NEMA SSL6
standard. The AL1692-10E applies to a wide range of dimmers,
including leading edge and trailing edge dimmer, to achieve deep
dimming down to 1%
