Designed for absolute maximum power density and high efficiency, Ericsson Power Modules' PKM4402NG is an intermediate bus converter (IBC) useable with a narrow input range.

The 475W/inch3 power density of the PKM4402NG packs two quarter bricks into the space of one, providing twice the power compared to previous generation of IBC products on the market. Accordingly, said the company, OEMs and end users save board space, design time and purchase costs by using just one quarter brick where previously two were required.

Touted to be the first in the industry to provide up to 660W in a quarter brick package, the PKM4402NG features a 38-55V input range, and is designed for use as an IBC by customers using a non-battery backup, nominal 48V input system.

The high output current (up to 63A) of the IBC provides the user with unprecedented available power levels at all line and load conditions even when the full input range is utilised, said the press release.

Suitable application areas for the PKM4402NG include computing, storage area networks, industrial computers, routers and blade servers. The device's high efficiency increases system reliability and reduces lifetime costs.

According to Ericsson Power Modules, the PKM4402NG has been designed using the most advanced technology available on the market. This, combined with the innovative use of different topologies that are optimised for maximizing the efficiency, led to this world record breaking design for power density, added the company.
