A special DC-to-DC converter is designed to supply low-power to the detector system of the J-PARC \(g-2\)/EDM experiment, which aims to measure the anomaly of the muon magnetic dipole moment, \(a_{\mu } = (g -2 ) / 2\). The important requirement of the DC-to-DC converter is that the stray magnetic field from the converter should be less than 30 \({ {\mu }}\)T to reach the experimental sensitivity of 450 ppb. The DC-to-DC converter contains one buck converter and three regulators, featured with a customary designed air-core inductor. The detailed design and test results for the voltage stability, stray magnetic field, and heat dissipation in vacuum are reported.
