Краткое описание:
36-Channel LED Driver with Independent PWM Control
Дополнительная информация
The IS31FL3237 is a constant current LED driver with 36 channels, each featuring independent PWM control. It operates with a selectable PWM frequency of 3kHz or 22kHz and supports a maximum output current of 38mA per channel, adjustable via an external resistor. The device features an I2C interface with an automatic address increment function and four selectable I2C addresses. Each channel's brightness can be modulated in 256 steps, and output current can be independently scaled by factors of 1, 1/2, 1/3, and 1/4.
