NCL30086BHDR2G ON Semiconductor

NCL30086BH Analog/Digital Dimmable Power Factor Corrected Quasi-Resonant Primary Side Current-Mode www.onsemi.com Controller for LED Lighting The NCL30086BH is a controller targeting isolated and nonisolated smartdimmable constantcurrent LED drivers. Designed to support flyback, buckboost, and SEPIC topologies, its SOIC10 proprietary currentcontrol algorithm provides nearunity power CASE 751BQ factor and tightly regulates a constant LED current from the primary side, thus eliminating the need for a secondaryside feedback circuitry MARKING DIAGRAM or an optocoupler. Housed in the SOIC10 which has the same body size as a standard L30086BH SOIC8, the NCL30086BH is specifically intended for very compact ALYW spaceefficient designs. The device is highly integrated with a minimum number of external components. A robust suite of safety protections is built in to simplify the design. To ensure reliable operation at elevated temperatures, a user configurable current L30086BH = Specific Device Code foldback circuit is also provided. In addition, it supports analog and A = Assembly Location PWM dimming with a dedicated dimming input intended to control L = Wafer Lot Y = Year the average LED current. W = Work Week Pintopin compatible to the NCL30086, the NCL30086BH = Pb-Free Package provides the same benefits with in addition, an increased resolution of the digital currentcontrol algorithm for a 75% reduction in the LED PIN CONNECTIONS current quantization ripple. 1 DIM NC Features ZCD V CC Quasiresonant Peak Currentmode Control Operation VS DRV Valley Lockout Optimizes Efficiency over the Line/Load Range COMP GND Constant Current Control with Primary Side Feedback SD CS (Top View) Tight LED Constant Current Regulation of 2% Typical Power Factor Correction ORDERING INFORMATION Analog or PWM dimming See detailed ordering and shipping information in the package Line Feedforward for Enhanced Regulation Accuracy dimensions section on page 29 of this data sheet.
