onsemi NCL3100x - LED driver

The NCL31000 is an intelligent LED driver targeting luminaire applications, with its companion NCL31001 designed for multichannel applications.

A highly efficient buck LED driver supports both high-bandwidth analog and PWM dimming down to zero current. Two auxiliary DC-DC converters are available 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 driver supports YellowDot™ Compliant Solutions, being Visible Light Communication Capable it enables indoor position location applications.
