We propose a 12-to-5 V DC-DC converter using a low-temperature co-fired ceramic (LTCC)-based multi-layer circuit technology. The converter using seven-layer LTCC includes an embedded metal layout strategy to achieve noise mitigation. The measured efficiency and maximum output ripple noise of the proposed converter prototype were 96.18% and 73.75 mV_pp, respectively. From the result of electromagnetic interference test, the proposed converter satisfied the IEC61000-6-3 Class B standard. © 2021 Institute of Electrical Engineers of Japan.
