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.
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.
