A special DC-to-DC converter is designed to supply low-power to the detector system of the J-PARC g-2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$g-2$$\end{document}/EDM experiment, which aims to measure the anomaly of the muon magnetic dipole moment, aμ=(g-2)/2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$a_{\mu } = (g -2 ) / 2$$\end{document}. The important requirement of the DC-to-DC converter is that the stray magnetic field from the converter should be less than 30 μ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${ {\mu }}$$\end{document}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.
