**Buck Converter: Basics, Working, Design and Operation** Designing a Buck Converter. STEP – 1. Determine the input voltage and the output voltage and current. The duty cycle of the converter is given by: DC = V out V in. STEP – 2. Determine the output power, that is, the product of the output voltage and current. This is also the input power, by the law of conservation of energy (though not exactly so – nothing is a hundred percent efficient!).

**AN1663: Designing a Buck Converter Renesas Electronics** If you chose a hysteretic buck converter instead of a voltage mode converter, the design process is similar.
