HOUSTON – APPLIED POWER ELECTRONICS CONFERENCE (APEC) – Mar. 21, 2022 – Murata today announced the development of the MYC0409, the industry’s highest power density(5.4kW/inch3) , 48 Vin divide-by-4 charge pump capacitor divider module with all passive components integrated in a low profile PSiP package. Capable of delivering up to 72 watts of power with peak efficiency of around 97-percent, the interleaved, switching capacitor architecture is based on Murata’s unique lossless charge pump technology, providing extremely low input and output ripple performance. The solution is presented in a compact footprint with 2.0 mm height, making it ideal for low profile applications and placement on the underside of system boards. MYC0409 devices can be connected in parallel to provide high power, high efficiency solutions suitable for a variety of 48V to 12V step-down conversion applications such as datacenters, networking routers, base stations and optical equipment. 

 

“5G and IoT data-driven applications are pushing the limits for datacenter and networking power requirements. Next-generation systems are already migrating to 48V bus systems due to interconnect and printed circuit board copper losses,” said Shuji Mikami, general manager of low power products department. “Previously, we released PE25204 as part of our FlexiCP™ portfolio, discrete charge pump IC, which is akin to a virtually lossless DC transformer. Now, we are unveiling the MYC0409 UltraCP™ charge pump capable of ultra-high efficiency conversion from 48 Vin bus in a low profile, compact PSiP package.”

Companies have traditionally relied upon brick converters to stepdown from 48V to the intermediate bus, usually 12V. The MYC0409 breaks the mold by enabling system architects to design high density, 48V converters in a smaller footprint with enhanced efficiency and low ripple performance. System designers have the flexibility to choose between creating a single high-power bulk 48V bus system with MYC0409 devices connected in parallel or distributing individual MYC0409 devices close to the point-of-load, thereby reducing system PCB copper losses.
