NCL30188BDR2G Description

Short technical summary and product information.

The NCL30188BDR2G from ON Semiconductor is a highly integrated controller designed for constant-current LED drivers. It supports various topologies including flyback, buck-boost, and SEPIC, enabling both isolated and non-isolated smart-dimmable LED applications.

 

This device features power factor correction and quasi-resonant peak current-mode control, providing tight LED current regulation of ±2% typical from the primary side, eliminating the need for secondary-side feedback circuitry. It operates with an 8.8V supply voltage and delivers up to 500mA output current. The controller includes a robust suite of protection features such as OVP on VCC, programmable over voltage/LED open circuit protection, cycle-by-cycle peak current limit, and thermal shutdown.

 

Designed for compact, space-efficient designs, the NCL30188BDR2G is housed in an 8-SOIC package and is intended for surface mount applications. It offers features like user-programmable NTC-based thermal foldback for reliable operation at elevated temperatures. The device is Pb-Free and Halide-Free.

 

Key specifications include a wide operating temperature range of -40°C to 125°C (TJ), a low start-up current of 13 µA typical, and a 300 mA / 500 mA totem pole driver with a 12V gate clamp.
