Murata has announced the development of the MYC0409, the industry’s highest power density (5.4 kW/inch3), 48 Vin divide-by-4 charge pump capacitor divider module with all passive components integrated into a low profile PSiP package. Capable of delivering up to 72 watts of power with a 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 48 to 12 V step-down conversion applications such as data centers, networking routers, base stations and optical equipment.
“5G and IoT data-driven applications are pushing the limits for data center and networking power requirements. Next-generation systems are already migrating to 48 V bus systems due to interconnect and printed circuit board copper losses,” said Shuji Mikami, general manager of the 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 step-down from 48 V to the intermediate bus, usually 12 V. The MYC0409 breaks the mold by enabling system architects to design high density, 48 V 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 48 V 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.
Key features of MYC0409
- The MYC0409 is designed to operate in a fixed divide-by-4 mode over an input voltage range of 20 to 60 V, which extends its usage to 24 to 36 V input applications typically used in consumer battery charging and industrial supplies.
- The charge pump-based DC-DC converter supports an output voltage range of 5 to 15 V with load currents of 6 A and up to 72 W delivered to the external load.
- Featuring an extended temperature range of -40 to +105°C, the MYC0409 is fully protected with input under-voltage, overcurrent protection and thermal shutdown fault detection.
Packaging and Availability
The MYC0409 measures 11.5 x 9.5 x 2.0 mm and is offered in Land-Grid-Array packaging (LGA).
