Hello everyone,
The attached buck converter uses the MOSFET in the low side, however the drawback is the floating output. This makes it easy to drive the MOSFET and even can be used as buck converter for input voltage as high as rectified mains because no high voltage capacitor is needed for the bootstrap.
1) Why isn't this topology as popular as the usual one ? Only because of the floating output ? Is there any issue I do not see ?
2) I do not see any problem in changing the output filter inductor at the cathode of the diode, am I right ?
Thank you for your time !
