Complete Connected LED Driver Power Solution NCL31000, NCL31001 Description The NCL31000 is a new member of the ON Semiconductor LED driver family specifically targeting luminaire applications. NCL31000 www.onsemi.com incorporates a high efficient buck LED driver. The LED driver supports both highbandwidth analog dimming and PWM dimming down to zero current. NCL31000 includes an integrated fixed 3V3 DCDC and one adjustable DCDC. A diagnostics block incorporates an ADC, which measures input and LED output currents, voltages, LED temperature, DC/DC voltages and currents. Fast safety QFN48 7x7, 0.5P mechanisms protect the critical blocks of the chip. The diagnostic CASE 485EP measurements are available together with a flexible status reporting and interrupt mechanism. NCL31001 is the same as NCL31000 except that it does not include both DCDC converters. The combination of MARKING DIAGRAM NCL31000 and NCL31001 is ideal for dual channel solutions. 1 NCL31 Features 000x Wide Input Voltage Range: 21.5 V to 57 V AWLYYWW Proprietary 100 W+ Applications Integrated 3.3 V Buck Convertor (Only for NCL31000) NCL31000 Integrated Adjustable Buck Convertor 2.5 24 V (Only for NCL31000) 1 Integrated High Efficiency Buck LED Driver NCL31 001x Adjustable Switching Frequency 44.4 kHz to 1 MHz AWLYYWW Deep Dimming to Zero with Accuracy of 0.1% Using Internal Precision 2.4 V Reference NCL31001 Best in Class Linearity High Modulation Bandwidth (~50 kHz) NCL31000x = Specific Device Code (x = I or S) Visual Light Communication Capable NCL31001x YellowDot Compliant A = Assembly Location WL = Wafer Lot Internal DIM DAC for Independent LED Control During YY = Year Microcontroller Reflashing (Warm Boot) WW = Work Week Low EMI Reference Design 2 I C/SPI Interface (I/S Suffix) High Accuracy Diagnostic Functions to Measure Voltages/Currents ORDERING INFORMATION See detailed ordering and shipping information on page 2 of Protection against LED Shorts & Opens this data sheet.
