Overview

The NCL30170 is a linear regulating constant current LED controller in smart lighting and phase-cut dimming application. The controller manages multiple series LED current in ON semiconductor’s proprietary auto-commutation topology with high CC regulation accuracy and superior performance in PF and THD. The device provides wide analog dimming range with linear dimming curve and low current consumption in the standby mode. In phase-cut dimming application, input current shape modulation provides both good PF and excellent dimmer compatibility. Self-biasing high-voltage regulator supplies stable IC bias voltage with fast startup time. The NCL30170 has several protections such as thermal shutdown, input over voltage protection, sensing resistor short protection and LED over current limit for high system reliability.
