Ericsson Power Modules' PKM4402NG is an intermediate bus converter (IBC) useable with a narrow input range that provides up to 660W in a quarter brick package. According to Ericsson, the high power density (475W/cubic inch) of the PKM4402NG packs two quarter bricks into the space of one, providing twice the power compared to previous generation of IBC products.
The PKM4402NG is optimized for use in a non-battery backup, nominal 48V input system. With a 38-55V input range, the PKM4402NG is also completely N+1 parallelable without external circuitry. Suitable application areas for the PKM4402NG include computing, storage area networks, industrial computers, routers and blade servers. The device's 97% efficiency contributes to system reliability and reduces lifetime costs.
Where previous-generation isolated converters provide 92-93% efficiency and up to 18A at 12Vout, these latest IBC devices from Ericsson have figures up to 97% efficiency and 63A, at all input voltages. The PKM4402NG is the latest addition to Ericsson Power Modules IBC line that includes the recently launched wide input range quarter bricks and the soon to be launched eighth and sixteenth bricks for both 36-75Vin and 38-55Vin. Additionally, Ericsson also offers low cost IBCs for applications with lower power needs, below 300W.
In OEM quantities of 1,000 pieces, the PKM4402NG is priced at US$60.00. Samples are now available.
