Краткое описание:
18-Channel LED Driver with Independent PWM Control
Дополнительная информация
The IS31FL3238 is an 18-channel constant current LED driver with independent PWM control for each channel. It features a selectable PWM frequency of 3kHz or 22kHz and supports 256 steps of PWM brightness control. Each channel's output current can be set by an external resistor and independently scaled. It operates over a wide voltage range of 2.7V to 5.5V and includes a software shutdown mode to reduce power consumption.
