New Advanced Bus Converter for High-Power Applications

Ericsson’s PKB4413DA is a low-profile, 408-W DC/DC converter module well suited for high-power, high-performance applications. Intended to provide point-of-load (POL) DC/DC converters with tightly regulated 12-V output at up to 34 A, the PKB4413DA’s five-pin, 1/8-brick footprint is compatible with the Distributed-power Open Standards Alliance’s (DOSA) standard. In addition, it has a full 36 to 75 V telecom input range. This combination makes it ideal for intermediate bus conversion in information and communication technologies (ICT) applications.Ericsson PKB4413DA

The PKB4413DA’s features, benefits, and specs:

  • Hybrid Regulated Ratio (HRR) technology minimizes power losses
  • Efficiency can be up to 96% with a 48-V input and 12-V output at half-load.
  • Standard eighth-brick format (2.30 × 0.89 × 0.52″)
  • I/O protection and operational features (e.g., input under-voltage shutdown, monotonic start-up, remote control, output over-voltage, over-temperature, and output short-circuit protection
  • Calculated MTBF of 8.5 million hours
  • Meets IEC/EN/UL60950-1 safety requirements

The PKB4413DA costs $36.15 in OEM quantities of 1,000 or more.

New Low-Profile, 450-W DC/DC Converter Module

Ericsson recently launched a low-profile, 450-W DC/DC converter module, which provides a 12-V output voltage at up to 37.5 A to point-of-load (POL) DC/DC converters. Offered in a five-pin 1/8-brick footprint, the new PKB4413D advanced bus converter has an input range from 36 to 60 V.Ericsson PKB 4413D

Ideal for intermediate bus conversion in Information and Communication Technologies (ICT) applications, the PKB4413D incorporates Ericsson’s cutting-edge HRR Hybrid Regulated Ratio (HRR) technology to deliver high-power conversion from a wide input voltage range while keeping power losses low. Offering class-leading performance in thermally challenging environments and delivering a typical efficiency of 96%, with a 48-V input and 12-V output at half-load, the module significantly reduces energy and cooling costs. Competitive products typically dissipate 18% or more of their input power at 30-A loads. Meeting the deployment requirements for distributed power and intermediate bus voltage architectures, the module particularly targets high-power and high-performance use in networking and telecommunications equipment, servers and data storage applications, as well as industrial equipment.

Features, specs, and benefits:

  • Industry-standard eighth-brick format, 58.4 × 22.7 × 13.2 mm (2.30 × 0.89 × 0.52″)
  • Offers up to 96% efficiency at 12-V output, significantly reducing energy and cooling costs
  • Provides 1500 V(dc) I/O isolation
  • Meets the safety requirements of IEC/EN/UL60950-1
  • Calculated MTBF of 8.5 million hours

The PKB4413D is priced at $39.00 in OEM quantities of 1,000 pieces or more.

Power Interface Module Simplifies Low-EMI Design in ATCA Applications

Ericsson recently announced the availability of the PIM4610PD power interface module (PIM), which simplifies low-EMI design in Advanced Telecom Computing Architecture (ATCA) applications. An extension of Ericsson’s 3E* PIM family, the new PIM4610PD has been optimized to simplify design in blade server-applications based on ATCA and PICMG 3.7 systems.

  • The PIM4610PD’s features and specs:

    Minimized ripple and noise characteristics have been minimized

  • Operates over an input range of 36 to 75 V
  • Delivers 864 W with a 54-V input, 768 W at 48 V, and 600 W at 37.5 V
  • Built-in digital monitoring and an extensive range of energy-monitoring functionalities via an I2C/PMBus interface
  • Protection against input transients, reverse polarity, over-temperature, over-current, input under-voltage, and inrush current
  • A well-controlled shutdown procedure that enables de-assertion of the Power Good pin when input power is below a certain level
  • Quarter-brick format, measuring 57.9 × 36.8 × 21.33 mm

The  PIM4610PD starts at $72 for OEM quantities.
