NCL30088BDR2G

The NCL30088BDR2G from ON Semiconductor is a highly integrated controller designed for isolated and non-isolated constant current LED drivers. It operates using Power Factor Corrected Quasi-Resonant Primary Side Current-Mode Control, optimizing efficiency.

This device provides tight LED constant current regulation of ±2% typical from the primary side, eliminating the need for secondary side feedback circuitry. Key features include line feedforward for enhanced regulation accuracy and a low start-up current. The controller is built with a robust suite of protection features, including OVP on VCC, programmable overvoltage/LED open circuit protection, cycle-by-cycle peak current limit, winding short circuit protection, secondary diode short protection, output short circuit protection, shorted current sense protection, user programmable NTC based thermal foldback, thermal shutdown, VCC undervoltage lockout, and brown-out protection.

Designed for very compact, space-efficient designs, the NCL30088BDR2G is suitable for applications such as integral LED bulbs and tubes, LED light engines, LED drivers/power supplies, and electronic control gear for LED lighting. It is housed in an 8-SOIC package and operates within a temperature range of -40°C to 125°C.

The NCL30088BDR2G is a specific version (B) that features auto-recovery protection mode and a 250 mV current regulation reference voltage, recommended for isolated converters and non-isolated converters with specific output voltage and input RMS conditions.
