6-Phase Boost Converter Design
Input 48–58V, output 72V nominal, 3.6kW, efficiency target 96%, enable via 3.3V logic.

Your goal: 6-phase interleaved boost, 48–58 V in to ~72 V out, 3.6 kW, 300–500 kHz, 96% target, 3.3 V enable. I’ve prepared a plan:
- Freeze specs: per-phase f_sw, ripple targets, UVLO/OVP/OCP/OTP, 3.3 V enable and soft-start.
- Choose architecture/control: 6-phase interleaved, current-share, per-phase sensing, fault latch.
- Size power stage: inductors (≤60% of Imax, ≤90% of Isat; ripple 20–40%), FETs/rectifiers, drivers, snubbers, IO caps, EMI filter.
- Capture schematic and select parts; implement enable/protections; generate BOM.
- Simulate (transient/efficiency/thermal), then PCB layout and reviews.
