there will be less power consumed driving the MOSFETs. If you use typical values for on
resistance, you get 0.106
W 0.054 W for 94% effi ciency.
High-effi ciency controllers frequently implement burst mode for low power output
situations. As the output power declines, the controller will produce a burst of pulses to
charge the output and then shut off the controller while the output slowly drops to the
low trip voltage where a new burst is output. This operation is very similar to how pulse
frequency modulation controllers operate. Instead of a single long pulse that changes the
frequency of the control, ...

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
