onsemi NCL31000ASGEVB LED Driver Evaluation Board

onsemi NCL31000ASGEVB LED Driver Evaluation Board is an Arduino-shield compatible demonstration platform for the NCL31000 Intelligent LED Driver. The NCL31000 supports both high-bandwidth analog dimming and PWM dimming down to zero current. The device 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.

onsemi NCL31000ASGEVB LED Driver Evaluation Board is designed to connect to an Arduino-compatible microcontroller board, which can be connected to a PC. A USB to I2C interface can also be used.
