BRIDGEWATER, USA: Enpirion announced the availability of two feature-rich voltage mode synchronous buck DC-DC converters: the 6A EN5364 and the 9A EN5394.
These low-power switch-mode converters are complete power systems on a chip (PwrSoC), achieving up to 93 percent efficiency and integrating the inductor, power switches, gate drive, controller, and loop compensation, all in tiny 8 mm x 11 mm x 1.85 mm packages.
The 9A EN5394 sets a new standard in power density by delivering 100 Watts per square inch (15 Watts per square centimeter).
Leading OEMs have widely adopted this technology and are already designing with Enpirion’s new 6A and 9A DC-DC converters. The parts meet the precise voltage and fast transient requirements of high-performance applications such as set-top boxes/HD DVRs, LAN/SAN adapter cards, audio/video equipment, optical networking, multi-function printers, test and measurement, embedded computing, storage, and servers.
“Power density is critical, especially as the number of application features and functions increase and the equipment form-factor shrinks,” said Paul O’Shea, Sr. Editor for Electronic Products magazine.
“Enpirion proves that they can meet the industry challenge for high efficiency and power density, with the introduction of the EN5364 and the 100 Watts per square inch EN5394 highly integrated power SoC,” said O’Shea.
Operating the EN5364 and EN5394 power devices requires very few external components, resulting in simplified board design and layout, as well as improved manufacturability and reliability.
The two parts are pin compatible, offering a scalable power solution that enables the user to easily tune to their design as the power requirements evolve. A rich set of features, including phase-lock operation and phase delay, facilitates ease of use in systems that are sensitive to ripple and beat frequencies.
