The NCL30185BDR2G from ON Semiconductor is a Power Factor Corrected Quasi-Resonant Primary Side Current-Mode Controller specifically designed for LED lighting applications. It supports isolated and non-isolated constant-current LED drivers and is suitable for flyback, buck-boost, and SEPIC topologies.
This controller offers tight LED constant current regulation of ±2% typical and features 3-step dimming (70/25/5%). It integrates a robust suite of protection features, including OVP on VCC, programmable over-voltage protection, cycle-by-cycle peak current limit, and thermal shutdown. The device operates over a wide Vcc range and includes a user-configurable current foldback circuit for reliable operation at elevated temperatures.
Housed in an 8-SOIC package, the NCL30185BDR2G is intended for very compact, space-efficient designs. It requires surface mount technology. The operating temperature range is -40°C to 125°C (TJ).
Key features include quasi-resonant peak current-mode control, valley lockout for optimized efficiency, and line feedforward for enhanced regulation accuracy. It also supports step dimming by toggling the main AC switch.
