6.2.1.2 Calculating Power Loss

  • Power loss at 25 A = 3.5 W (Figure 1)
  • Normalized power loss for input voltage ≈ 1.03 (Figure 7)
  • Normalized power loss for output voltage ≈ 0.90 (Figure 8)
  • Normalized power loss for switching frequency ≈ 1.15 (Figure 6)
  • Normalized power loss for output inductor ≈ 1.03 (Figure 9)
  • Final calculated power loss = 3.5 W × 1.03 × 0.90 × 1.15 × 1.03 ≈ 3.84 W
