    Hi Matsumoto-san

    Yes the parallel connection is okay if the customer is not concerned about brightness difference in each string due to LED mis-matching. The switching waveforms you show look okay. If the customer has I2C capability I would recommend the LM3697 for the three sting driver.

    Best regards,
