DIMMABLE LED DRIVER
The AL1692-30B 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
AL1692-30B 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 AL1692-30B LED driver integrates a 500V/3A high voltage
MOSFET. It can cover 120Vac triac dimmable applications with
eliminating the external high voltage MOSFET and Varistor, which will
reduce the system BOM cost. The AL1692-30B 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 AL1692-30B dimming curve is compliant with the NEMA SSL6
standard. The AL1692-30B applies to a wide range of dimmers,
including leading edge and trailing edge dimmer, to achieve deep
dimming down to 1%.
