Eng Lih Khaw
Expert 2000 points

Part Number: LP5569

Hi,

I've two questions regarding LP5569:

  1. This device has two PWM scheme? One is 8-bit PWM which can be controlled via I2C. Another PWM is via EN/PWM pin, correct? and what are the differences?
  2. Can EN/PWM pin be left floating?

Thanks

    Hi,

    You're correct. This driver has independent PWM control for each channel and you can achieve Master Fader Control for multiple LEDs together through EN/PWM. Please refer to datasheet 8.3.1.2.3.

    lease don't leave this floating.

    Please help to click "Resolve" if the problem is solved.

    Thanks.
    Regards,
