Rochester Electronics PMIC - LED Drivers NCL30186ADR2G

The NCL30186ADR2G is a highly integrated LED driver controller designed for both isolated and non-isolated "smart-dimmable" applications. It supports various topologies, including flyback, buck-boost, and SEPIC, and utilizes a proprietary current-control algorithm to achieve near-unity power factor while regulating a constant LED current from the primary side, eliminating the need for secondary-side feedback circuitry. This device is housed in a compact SOIC10 package, making it suitable for space-constrained designs. It features robust protection mechanisms, including brown-out detection, over-voltage protection, and cycle-by-cycle peak current limiting, ensuring reliable operation under various conditions. The NCL30186ADR2G supports both analog and PWM dimming through a dedicated input, allowing for flexible control of average LED current. With a typical LED current regulation accuracy of ¬±2% and a wide operating temperature range of -40 to 125¬8C, this LED driver is well-suited for applications such as integral LED bulbs, LED light engines, and smart LED lighting systems. It is also pin-to-pin compatible with the NCL30086, offering enhanced digital current-control resolution.
