Charge pumps have been simple, useful tools for voltage conversion, but they have also had their attendant downsides, including low efficiency and high EMI levels. Here at 2022, Murata has upended those assumptions with a new charge pump architecture that's embodied in a small but growing product family of devices providing compact, highly efficient voltage division for a variety of applications. In this exclusive from-the-show-floor interview, Murata's VP of power products explains the technology and some of its application.
I spoke with Vice President of Power at Murata about the company's technology and the new UltraCP MYC0409. The MYC0409 is 48-V, divide-by-4 charge pump capacitor divider in a fully integrated module. It can deliver up to 72 W of power with peak efficiency of 97%. The device can be connected in parallel to provide high-power, high-efficiency solutions suitable for a variety of 48-V to 12-V step-downconversion applications such as networking routers, base stations, data centers, and optical equipment.
