NCL30088DDR2G ON Semiconductor

NCL30088 Power Factor Corrected Quasi-Resonant Primary Side Current-Mode Controller for LED Lighting www.onsemi.com with Thermal Foldback The NCL30088 is a power factor corrected flyback controller 8 targeting isolated and nonisolated constant current LED drivers. The 1 controller operates in a quasiresonant mode to provide optimal SOIC8 NB efficiency. Thanks to a novel control method, the device is able to CASE 751 tightly regulate a constant LED current from the primary side. This removes the need for secondary side feedback circuitry, biasing and an MARKING DIAGRAM optocoupler. 8 The device is highly integrated with a minimum number of external L30088x components. A robust suite of safety protection is built in to simplify ALYW the design. This device is specifically intended for very compact, space efficient designs. 1 Features L30088x = Specific Device Code x = A, B, C, D Quasiresonant Peak Currentmode Control Operation A = Assembly Location Constant Current Control with Primary Side Feedback L = Wafer Lot Y = Year Tight LED Constant Current Regulation of 2% Typical W = Work Week Power Factor Correction = Pb-Free Package Line Feedforward for Enhanced Regulation Accuracy Low Startup Current (13 A typ.)
