LM43600: in case of SYNC input(external clock input)

Part Number: LM43600

Hi all

Would you mind if we ask LM43600?

In case of SYNC input(external clock input), if the light is light load, will the mode be PFM mode?
We would like to use forced PWM mode in case of SYNC input(external clock input).
Should we use LM53600-Q1 instead of LM43600?

Kind regards,

Hirotaka Matsumoto

    We guess that your days are so busy, however could you let us know your reply?

    Kind regards,

    Hello Matsumoto-san,

    We apologize for the delay.

    The LM53600-Q1 does have true forced PWM mode but only works with standard BOM with an output voltage range of 3.3 V to 6 V. If your output voltage is in this range, the LM53600-Q1 does exactly what you want.

    The LM43600 does not have a true FPWM mode.
