Designing a Multi-Phase Buck Converter with Digital Controllers

Luckily such a device already exists, and it’s called a buck converter or step down voltage regulators. It’s a type of DC-DC converter, so it accomplishes the task using a few transistor switches and an inductor. A typical buck converter circuit is shown in the above image. It’s quite similar to a boost converter, but the … See more The working of a buck converter can be broken down into a few steps. STEP – 1: The switch turns on and lets current flow to the output capacitor, charging it up. Since the voltage across the capacitor cannot rise instantly, … See more MOSFET Since the switch is on the high side, using an N channel MOSFET or an NPN bipolar wouldn’t work, unless we have a bootstrapped gate driver.
