PCA9635PW

NXP  PCA9635PW  发光二极管驱动器, 16输出, 2.3V-5.5V输入, 1MHz开关, 5.5V/25mA输出, TSSOP-28

The is a 16-bit Fm+ I²C-bus LED Driver optimized for red/green/blue/amber RGBA colour mixing applications. Each LED output has its own 8-bit resolution 256 steps fixed frequency individual PWM controller that operates at 97kHz with a duty cycle that is adjustable from 0 to 99.6% to allow the LED to be set to a specific brightness value. An additional 8-bit resolution 256 steps Group PWM controller has both a fixed frequency of 190Hz and an adjustable frequency between 24Hz to once every 10.73seconds with a duty cycle that is adjustable from 0 to 99.6% that is used to either dim or blink all LEDs with the same value.
