Plano, Tex. Ericsson Power Modules has released a surface-mount version of its PKU series of DC/DC converters. The PKU-SI addresses the industry's need for smaller power supplies particularly in highly integrated systems across a broad range of telecommunications and datacommunication equipment.
The PKU-SI series consist of the PKU4510 SI (48Vin/ 3.3V/15A 50 Wout), PKU4511 SI (48Vin/5 V/10A 50 Wout) and PKU4515 SI (48Vin/ 15V/3.3A 50 Wout). These modules feature a wide output adjustment range of, for example, 3.3 V +10/-40 percent. For safety, the modules provide a 1500-V input-to-output isolation rating and feature protection against over-temperature, output short circuit, and output over-voltage.
The PKU-SI is DOSA (Distributed-power Open Standards Alliance) compatible. The same board is used for PI and SI versions of the PKU series, which increases the flexibility and speed of manufacturing and contributes to reduced lead times, said Ericsson. In addition, the module's high-efficiency results in lower power dissipation, reduced heat build up, and lower power consumption, all contributing to lower total cost of ownership, according to the company.
The PKU-SI series leverages Ericsson's MacroDens modules and Floating Inserted Pins (FIP) concept. Use of FIP ensures that all the connecting pins remain in place and are aligned during second or third reflow soldering. The pins are also manufactured with very tight tolerances, guaranteeing co-planarity and mechanical accuracy, said Ericsson.
Pricing: $24.10 in OEM quantities.
