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 suitable 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, saving 40% of the space required.
The converter has a high efficiency of typically 96.1% (at 48Vin, half load), which means that it saves energy and reduces cooling requirements, cutting TCO. It is said to be 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 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.
The PKU4217D is provided in an industry-standard low-profile sixteenth-brick form factor, measuring 33.02 x 22.86 x 11.30mm (1.3 x 0.9 x 0.44in). It is available optionally with a baseplate, or as a surface mounted device (SMD) version.
The module meets safety requirements according to IEC/EN/UL 62368-1.
