Plano, Tex. Ericsson Power Modules has expanded its PKM-E series with three models that provide additional output voltage ranges, higher current, and more power for telecommunications and data equipment in the areas of distributed power architecture, wireless networks, enterprise networks, access and optical networks, industrial equipment, and the latest generation of ICs including DSPs, FPGAs, and ASICs.
The PKM-E series power modules include the PKM4515ZE PI (48 Vinput/ 24 V/2.1 A 50 Woutput) the PKM4619E PI (48 Vinput/ 2.5 V/25 A 62.5 Woutput), and the PKM4810E PI (48 Vinput/ 3.3 V/25 A 82.5 Woutput). These DC/DC modules feature high efficiency, typically 92 percent at 3.3-V out half load, and operate over an input voltage range of 36 to 75 Vdc. They feature remote on/off, output voltage adjustment, remote sense, current protection, overvoltage protection, and overtemperature protection.
The PKM-E family enables users to replace an existing quarter-brick part with a high reliability PKM-E with a 25 percent lower cost. Use of a single-side component mounting design contributes to its lower cost. In addition, a specially developed magnetic design contributes to more power.
With a height of 8.5 mm (0.33 in.), the DC/DC modules are suitable for low-profile applications. A heat sink (HS) option is available for applications where cold wall mounting is deployed. The modules offer a reliability figure of 1.5 million hours mean time between failure (MTBF) at 40°C. The modules are RoHS compliant.
Pricing: The PKM4515ZE PI is priced at $21.46, and the PKM4619E PI and PKM4810E PI devices are priced at $24.68 in OEM quantities.
