onsemi NCL31000/1 - Intelligent LED Driver
NCL31000/1 YellowDot™ compliant intelligent LED Driver, with precision dimming, diagnostics and power metrology
The NCL31000 is an intelligent LED driver targeting luminaire applications. The NCL31000 incorporates a high efficiency buck LED driver that supports both high-bandwidth analog and PWM dimming down to zero current. Two auxiliary DC-DC converters are included to power a microcontroller and other sensors. Diagnostics are included to measure input and output current and voltage, LED temperature and DC-DC voltages. The device is ideal for YellowDot™ LED drivers.
The NCL31001 is an intelligent LED driver, designed to be coupled with the NCL31000 in multi-channel applications. Enabling dynamically tunable luminaires such as dual channel human centric lighting, therapeutic lighting, agriculture, and other multiple color blending applications. The NCL31001 incorporates a high efficiency buck LED driver that supports both high-bandwidth analog and PWM dimming down to zero current. Diagnostics are included to measure input and output currents and voltages, and LED temperature.
