Simulate a powerful 60V to 12V synchronous buck converter step-by-step in LTspice!
In this beginner-to-intermediate power electronics tutorial, we cover:
How the bootstrap circuit magically drives the high-side N-channel MOSFET
Synchronous rectification for better efficiency
Output filter (inductor + capacitors) and load resistor changes → watch Vout respond instantly!
Why open-loop isn't enough in real life → introducing closed-loop feedback basics (error amp + reference)
Teaser: Next video dives deep into op-amps, compensation, and Bode plots for stable control!
Perfect for electronics students, hobbyists, or anyone designing DC-DC converters.
We use discrete components + bootstrap for a realistic non-isolated synchronous buck.
