| Component | Value | Rating | Notes |
|---|---|---|---|
| Main Switch (Q1) | Silicon MOSFET | 62V / 8.6A | Low Rds(on), fast switching |
| Rectifier (D1) | SiC Schottky | 62V / 7.5A | Fast recovery, low Qrr |
| Inductor (L1) | 60.0 μH | 5.8A sat | Powdered Iron core |
| Output Cap (Cout) | 38 μF | 18V | ESR ≤ 1 mΩ |
| Input Cap (Cin) | 57 μF | 60V | Low ESR, high ripple rating |
