ncl31000: intelligent led driver, yellowdot™ compliant, with precision dimming, diagnostics and power metrology-凯发登录


rev. 1 (1374kb)


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  is a reduced-feature version to enable multi-channel solutions.
