AL16937 BUCK DIMMABLE LED DRIVER Description Pin Assignments NEW PRODUCT The AL16937 is a high performance, high power factor, high efficiency, and high current precision buck dimmable LED driver for triac dimmable LED lamp applications. The AL16937 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. (Top View) The AL16937 LED driver integrates 400V/3A MOSFET, which is suitable for 120VAC applications. The AL16937 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. 7 D 3 6 CS 4 5 NC VCC 1 RT 2 COMP GND SO-7 The AL16937 dimming curve is compliant with the NEMA SSL6 standard. The AL16937 applies to a wide range of dimmers, including leading edge and trailing edge dimmer, to achieve deep dimming down to 1%. Applications The AL16937 is available in SO-7 package.   Mains Dimmable LED Lamps Offline LED Power Supply Driver Features      Tight Current Sense Tolerance : ± 3% Low Startup Current: 100µA Typical Low Operation Current: 210µA (Switching Frequency at 4kHz) Single Winding Inductor Wide Range of Dimmer Compatibility    Integration of 400V/3A MOSFET NEMA SSL6 Dimming Curve Compliant Internal Protections  Under Voltage Lockout (UVLO)  Leading-Edge Blanking (LEB)  Cycle-By-Cycle Over Current Protection (OCP)  Output Short Protection (OSP)  Thermal Foldback Protection (TFP)  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.
