Краткое описание:
High-Efficiency White LED Driver with Programmable Ambient Light Sensing and I2C
Дополнительная информация
The LM3532 is a 500-kHz fixed frequency asynchronous boost converter providing power for 3 high-voltage, low-side current sinks. It features an I2C-compatible interface, independent current control for three channels, and dual ambient light sensor inputs with an internal 8-bit ADC. The device supports up to 40V per string with 90% efficiency and offers 256 levels of logarithmic or linear brightness control with 14-bit equivalent dimming.
