Provides cutting edge of power density in telecom and datacom applications – delivering valuable space savings, without compromising on efficiency

Flex Power Modules introduces industry’s smallest 260W DC-DC converter in a sixteenth-brick footprint, saving 40% in space requirements.

It can provide output power up to 260W, at an output voltage of 10.4V. This means it is the world’s smallest converter available in the market that can deliver this level of power.

The PKU4217D is an isolated intermediate bus converter (IBC) for supplying point-of-load (PoL) regulators. It delivers market-leading power density in a compact module, making it ideal for telecoms and datacom applications that require extremely high power delivery within small footprints. For these sectors, the PKU4217D can replace existing eighth-brick converters, thus saving 40% of the space required.

The new converter has a high efficiency of typically 96.1% (at 48Vin, half load). This means it saves energy and reduces cooling requirements, thus cutting TCO. It is the industry’s first converter to use HRR technology in a sixteenth-brick module, which has increased the output power achievable by around 60W, as well as increasing efficiency compared to an eighth-brick module without Hybrid Regulated Ratio (HRR).

The module has an input voltage range of 36V to 60V, and provides isolation of 2250V, making it suitable for Power over Ethernet (PoE) applications. Power output is up to 25A or 260W, at 10.4Vout.

Key Features

  • High efficiency, typical 96.1% at 48Vin, half load
  • 2250 Vdc input to output isolation
  • Pre-bias start up
  • Meets safety requirements according to IEC/EN/UL
    62368-1
  • MTBF 11.80 Million hours
