LM61440-Q1: available Dropout function in FPWM mode?

Hi,

According to datasheet P.27 "8.4.3.5 Dropout", we can find the following sentence.

"Instead of allowing the output voltage to drop, the LM61440 extends on-time past the end of the clock cycle until needed peak inductor current is achieved."

Is this still available on F-PWM mode? I want to confirm it.

Thanks and best regards,
