What it calculates

The “DC-DC Buck Converter” calculator computes Output voltage Vout in V from 5 parameters: input voltage vin (V), duty cycle d (%), switching frequency (kHz), inductor inductance (µH), load current (A).

A standard physics formula used in educational and engineering tasks.

Example calculation

With parameters Input voltage Vin = 12 V, Duty cycle D = 50 %, Switching frequency = 100 kHz, Inductor inductance = 47 µH, Load current = 2 A the result is 6 V (Ideal lossless converter in continuous conduction mode).
