NCL30186DDR2G

Overview

The NCL30186DDR2G is an LED lighting controller IC from onsemi, designed for isolated and non-isolated smart dimming constant current drivers. It supports flyback, buck-boost, and SEPIC topologies in a 10-SOIC package. The device features quasi-resonant peak current mode control with valley locking to optimize efficiency across line and load ranges. It achieves near unity power factor correction and precise primary-side constant LED current regulation without secondary feedback. Key electrical parameters include a supply voltage range of 8.8V to 25.5V, operation temperatures from -40°C to +125°C, and support for analog and PWM dimming via a dedicated DIM pin.

Feature Summary

Primary-side constant current control eliminates the need for optocouplers or secondary feedback circuits.
Quasi-resonant peak current mode control with valley locking optimizes switching efficiency.
Integrated thermal foldback circuitry ensures reliable operation under high-temperature conditions.
Comprehensive protection suite includes overvoltage, overcurrent, open-loop, and short-circuit safeguards.

Applications

Isolated and non-isolated smart dimming LED drivers
Compact LED lighting fixtures utilizing flyback, buck-boost, or SEPIC topologies
LED bulbs and tubes requiring high power factor and low standby power

Procurement Notes

Verify that the specific suffix DDR2G corresponds to the 10-SOIC package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure compatibility with the required isolation topology and dimming interface specifications for the target application design.

Selection Notes

Select this component for designs prioritizing high power factor and precise current regulation without secondary sensing. It is suitable for applications requiring integrated thermal management and flexible dimming capabilities. Evaluate the 10-SOIC footprint constraints against available PCB space requirements.
