NCL30170BDR2G ON Semiconductor

NCL30170 Direct AC Drive LED Driver for Power Factor Correction and Precise Constant Current Regulation www.onsemi.com The NCL30170 is a linear regulating constant current LED controller in smart lighting and phasecut dimming application. The controller manages multiple series LED current in ONSemiconductors proprietary autocommutation topology with high CC regulation accuracy and superior performance in PF and THD. The device provides wide analog dimming range with linear SOIC10 R2 SUFFIX dimming curve and low current consumption in the standby mode. In CASE 751EE phasecut dimming application, input current shape modulation provides both good PF and excellent dimmer compatibility. Selfbiasing highvoltage regulator supplies stable IC bias voltage MARKING DIAGRAM 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.
