Hybrid relays are changing the way we think about switching inside electronic circuits. By combining the fast response of solid-state components with the reliability of mechanical contacts, these ...

A new reference design developed by ROHM Semiconductor uses a single microcontroller (MCU) to control both sides of the AC-DC power supply — the power-factor-correction (PFC) AC-DC converter stage and ...

Portable DAC/AMPs have become essential for audiophiles who want desktop-level performance on the go, and Campfire Audio’s Relay DAC/AMP aims to deliver just that. Compact, beautifully built, and ...

At $229, the Campfire Audio Relay dongle DAC/amp delivers 4 Vrms output, premium build, and precise sound. Campfire Audio has been on a tear this year, dropping new IEMs left and right—including the ...
