The device operates in basic boost topology. The converter's buck switches (A1 and A2) are not switching during this mode. Switch A1 is always closed to allow current flow from the input into the ...

Inside the Circuit You can find the files on GitHub, as usual. I started the supply voltage (V1) at 15 V. M1, D1, L1, C1, and RL are essentially the same as the basic buck circuit seen last time.

Figure 2 shows a 5V power supply backed up by a battery-powered, LTC3778-controlled power supply. The synchronous, bidirectional LTC3778 buck circuit acts as a battery-to-5V converter if the main 5V ...

[Great Scott] should win an award for quickest explanation of a buck converter. Clocking in at five and a half minutes, the video clearly shows the operating principles behind the device. It starts… ...
