NCL31001

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 incorporates a high efficient buck LED driver. The LED driver supports both high−bandwidth analog dimming and PWM dimming down to zero current. NCL31000 includes an integrated fixed 3V3 DC−DC and one adjustable DC−DC. A diagnostics block incorporates an ADC, which measures input and LED output currents, voltages, LED temperature, DC/DC voltages and currents. Fast safety mechanisms protect the critical blocks of the chip. The diagnostic 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 DC−DC converters. The combination of NCL31000 and NCL31001 is ideal for dual channel solutions.
