NCL30288BSNT1G ON Semiconductor

NCL30288 Power Factor Corrected Quasi-Resonant Primary Side Current-Mode Controller for LED Lighting www.onsemi.com The NCL30288 is a compact driver for powerfactor corrected flyback and nonisolated buckboost and SEPIC converters. The controller operates in a quasiresonant mode to provide optimal efficiency, and embeds a proprietary control method which allows the LED current to be tightly regulated from the primary side, thus 1 eliminating the need for a secondaryside feedback circuitry and for TSOP6 an optocoupler. CASE 318G02 Housed in a TSOP6 package, the device is highly integrated with a minimum number of external components. A robust suite of safety MARKING DIAGRAM protection is built in to simplify the design. This device is specifically intended for very compact space efficient designs. 2T3AYW Features Quasiresonant Peak Currentmode Control Operation 1 Constant Current Control with Primary Side Feedback 2T3 = Specific Device Code Tight LED Constant Current Regulation of 2% typical A =Assembly Location NearUnity Power Factor (>0.95 typically) Y = Year Optimized for Line Widerange Applications W = Work Week = PbFree Package Line Feedforward for Enhanced Regulation Accuracy (Note: Microdot may be in either location) Low Startup Current (10 A typ.)
