onsemi NCL31000 and NCL31001 LED Drivers are intelligent LED drivers targeting luminaire applications. The NCL31000 and NCL31001 LED drivers support high-bandwidth analog and PWM dimming to zero current. The NCL31000 integrates a fixed 3.3V DC-DC and an adjustable 2.5V to 24.0V DC-DC Buck Converters. 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 device. The diagnostic measurements are available together with a flexible status reporting and interrupt mechanism. The NCL31001 is the same as the NCL31000 except that it does not include the DC-DC converters.
The onsemi NCL31000 and NCL31001 LED Drivers enable dynamically tuneable luminaires such as dual-channel human-centric lighting, therapeutic lighting, agriculture, and other multiple color blending applications. These devices are offered in a 7.0mm x 7.0mm QFN-48 package.
