LMR16006 is a non-sync mode，when the buck regulator works in CCM , how to charge the Cboot cap?
-when the high-side MOS open, CBoot cap discharges,
when high-side MOS close, the inductor L1 current began to flow through the diode D1, and the SW is clamped to -0.7V ,
so if the WinFET opens to charge the Cboot, no current flows because the SW point is clamped to -0.7V ，so how to charge the Cboot cap ,pls show me
thanks
Thanks
"The Cboot will be charged if SW node can be pull low close to 0V."
I still can not figure out this ；
check as the following waveform from the datasheet of LMR 16006
As your mean: when SW node close to 0V , then charge the Cboot , but as the above waveform ,the △t is too small ，
so how to ensure to fully charge the Cboot ? is that mean the Cboot Charging just only take little time ?
pls
thks
