產品總覽
The PCA9685PW is an I²C-bus controlled 16-channel LED controller optimized for LCD RGBA colour backlighting applications. Each LED output has its own 12-bit resolution (4096 steps) fixed frequency individual PWM controller that operates at a programmable frequency from a typical of 40 Hz to 1000 Hz with a duty cycle that is adjustable from 0 % to 100 % to allow the LED to be set to a specific brightness value. All outputs are set to the same PWM frequency.
- Programmable LED brightness
- Programmable LED turn-on time to help reduce EMI
- 25 MHz typical internal oscillator requires no external components
- Internal power-on reset
- Noise filter on SDA/SCL inputs
- Edge rate control on outputs
- No output glitches on power-up
