AL1696 HIGHLY INTEGRATION OFFLINE DIMMABLE LED DRIVER Description Pin Assignments The AL1696 is a highly integrated high power factor constant current converter for mains dimmable LED driver applications. The AL1696 (Top View) controls the system operating in boundary conduction mode (BCM) to ease in EMI/EMC qualification and testing to meet the latest 7 1 D NC regulatory standards. NC 2 VCC The AL1696 with build-in MOSFET solution reduces the bill of 3 6 CS material (BOM) cost by eliminating the need of auxiliary winding and 4 5 RT GND external high voltage MOSFET. The AL1696 can be compatible with a wide range of dimmers SO-7 including leading edge and trailing edge dimmers. Some dimmers can achieve deep dimming down to 1%. The AL1696 dimming curve is Applications compliant with the standard of NEMA SSL6. Mains Dimmable LED Lamps Offline LED Power Supply Driver The AL1696 is available in SO-7 package, which provides an extra pin spacing between the high voltage MOSFETs drain and low voltage pins to increase electricity isolation. Features Internal MOSFET up to 300V/3A, 400V/3A, 500V/2A, 600V/2A Tight Current Sense Tolerance: 3% Low Startup Current: 150A Low Operation Current: 120A (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.
