Hi all
Would you mind if we ask LMR61428?
In case of light load, does LMR61428 operate PFM function?
Is it possible to use as fixed PWM function?
Kind regards,
Hirotaka Matsumoto

This is a gated oscillator type of control. At light load the oscillator will switch on very briefly to charge the output capacitor.
So, you can think of it as a type of PFM.
It does not have a forced PWM mode.
