In this video, we upgrade the buck converter design by adding a bootstrap high-side MOSFET driver circuit. Learn how bootstrap gate driving works, how the capacitor charges, how the floating supply is created, and how high-side switching is achieved in real buck converters and SMPS designs.
We explain the complete bootstrap operation step by step with waveforms, switching states, and practical design insights. This is essential knowledge for anyone designing synchronous buck converters, half-bridge drivers, or power electronics hardware.
Perfect for engineering students, circuit designers, and power electronics learners who want to move from theory to real driver implementation.
This is Part 2 of the Buck Converter series.
Watch step-by-step:
1. Why high-side N-MOS needs bootstrap (theory recap)
2. How the bootstrap capacitor + diode creates floating gate supply.
3. LT spice simulation of bootstrapping.
