Ericsson has unleashed two sixteenth-brick DC/DC converters that are designed to power 60-65W applications. The PKU4619 and PKU4710 are intended for telecom and datacom systems and equipment, and applications in power industrial, process control, test and many more.

The devices provide designers with quick and reliable board-mounted power solutions that tackle increasing demands for shorter time-to-market, the company noted.

With an input voltage range of 36-75V, the PKU4619 and PKU4710 provide outputs of 2.5V/25A and 3.3V/20A, delivering output power of 62.5W and 66W, respectively. The products are ideal for applications such as mini-base stations and provide customers with a simple solution when upgrading 50W boards to 60W.

PKU4619 and PKU4710

The DC/DC converters are designed to power 60-65W applications.

Due to their industry-standard footprint (33 x 22.9mm) and height of 8.8mm, the duo can be used in low-profile applications when build height is critical. In addition, the devices' low profile, combined with high efficiency, makes them highly suitable for applications with reduced airflow, stated Ericsson. In a natural convection environment, full power can be delivered up to 40C and, with 3m/s airflow, up to 80C.

Offering a Mean-Time-Before-Failure (MTBF) of more than 3.6 million hours, the PKU4619 and PKU4710 meet safety requirements according to IEC/EN/UL 60950-1, offer input/output isolation of 1500V(dc) with protection features including output-overvoltage protection, input undervoltage shutdown, overtemperature protection and output short circuit protection.

The devices are also available in both through-hole (PI version) and surface-mount (SI version) types. The price of the PKU4619 and PKU4710 is $18.70 each, in OEM quantities.
