AL1696 HIGHLY INTEGRATION OFFLINE DIMMABLE LED DRIVER Description The AL1696 is a highly integrated high power factor constant current converter for mains dimmable LED driver applications. The AL1696 controls the system operating in boundary conduction mode (BCM) to ease in EMI/EMC qualification and testing to meet the latest regulatory standards. The AL1696 with build-in MOSFET solution reduces the bill of material (BOM) cost by eliminating the need of auxiliary winding and external high volta.

AL1696 HIGHLY INTEGRATION OFFLINE DIMMABLE LED DRIVER Description The AL1696 is a highly integrated high power factor constant current converter for mains dimmable LED driver applications. The AL1696 controls the system operating in boundary conduction mode (BCM) to ease in EMI/EMC qualification and testing to meet the latest regulatory standards. The AL1696 with build-in MOSFET solution reduces the bill of material (BOM) cost by eliminating the need of auxiliary winding and external high voltage MOSFET. Pin Assignments (Top View) NC 1 NC 2 CS 3 GND 4 7D 6 VCC 5 RT The AL1696 can be compatible with a wide range of dimmers including leading edge and trailing edge dimmers. Some dimmers can achieve deep dimming down to 1%. The AL1696 dimming curve is compliant with the standard of NEMA SSL6. The AL1696 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. SO-7 Applications  Mains Dimmable LED Lamps  Offline LED Power Supply Driver Features  Internal MOSFET up to 300V/3A, 400V/3A, 500V/2A, 600V/2A  Tight Current Sense Tolerance: ±3%  Low Startup Current: 150µA  Low Operation Current: 120µA (Switching Frequency at 5kHz)  Single Winding Inductor  Wide Range of Dimmer Compatibility  Dimming Curve Compliant with NEMA SSL6  Internal Protections  Under Voltage Lockout (UVLO)  Leading-Edge Blanking (LEB)  Cycle-by-cycle Over Current Protection (OCP)  Output Short Protection (OSP)  Over-Temperature Protection (OTP)  SO-7 Package  Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device (Note 3) Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.
