Buck Boost Sepic Converter filter design calculator

Calculate component values for a Buck Boost Sepic Converter switch-mode power supply filter.

Inputs

  • Maximum input voltage (V) — default 14
  • Minimum input voltage (V) — default 10
  • Output voltage (V) — default 5
  • Output current (A) — default 2
  • Switching frequency (kHz) — default 40
  • Inductor current ripple (%) — default 30
  • Output voltage ripple (V) — default 0.05
  • Diode voltage drop (V) — default 0.7

Calculated outputs

  • Inductance L1 (uH)
  • Inductance L2 (uH)
  • Middle Coupling Capacitor C1 (uF)
  • Output Capacitance Co (uF)

All results are in micro (µ).
