DIMMABLE LED DRIVER

Description

Pin Assignments

The AL1698 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 AL1698

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 AL1698 LED driver has a built-in high voltage JFET, which

provides the system fast start-up time and enables users an easy and

stable V_CCsupply design. The AL1698 also integrates a 600V/2A high

voltage MOSFET. It can cover 230V_ACtriac dimmable applications

with eliminating the external high voltage MOSFET and V_CCstartup

resistors, which will reduce the system BOM cost. The AL1698 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.

Applications



Mains Dimmable LED Lamps

Offline LED Power Supply Driver

The AL1698 dimming curve is compliant with the NEMA SSL6

standard. The AL1698 applies to a wide range of dimmers, including

leading edge and trailing edge dimmer, to achieve deep dimming

down to 1%.

The AL1698 is available in SO-7 package.
