AL1697
High PF, Offline Dimmable LED Driver with Internal High-Voltage MOSFET
Description
The AL1697 is a high performance, high power factor, high efficiency
and high precision buck-boost LED driver for mains dimmable LED
lamp applications. The AL1697 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 AL1697 with built in MOSFET solution reduces the bill of material
(BOM) cost by eliminating the need of auxiliary winding and an
external high voltage MOSFET. The AL1697 has extensive protection
features to enhance system safety and reliability. The AL1697 starts
reducing output current when the driver’s temperature is higher than
the built-in thermal foldback protection trigger point.

The AL1697 applies to a wide range of dimmers including leading
edge and trailing edge dimmer. Some can achieve deep dimming
down to 1%. The AL1697 dimming curve is compliant with the NEMA
SSL6 standard.
The AL1697 is available in SO-7 package, which provides an extra
pin spacing between the high voltage MOSFET’s drain and low
voltage pins to increase electricity isolation.
