Ericsson has introduced two new sixteenth-brick format DC-DC converters that provide designers with quick and reliable board-mounted power solutions, addressing increasing demands for shorter time-to-market. Designed to power 60 to 65W applications, the new PKU4619 and PKU4710 are primarily designed for telecom and datacom systems and equipment, but are also suitable for use in power industrial, process control, test and many other applications.

Sixteenth-brick DC-DC converters provide designers with quick and reliable board-mounted power solutions for meet time-to-market demands. Low-profile and high-efficiency modules ideal for use in mini-base-stations and other telecom and datacom applications. New converter duo enable fast and easy upgrade from 50W boards to 60W and beyond

“As system designs continue their use of increasingly powerful processors, FPGAs and memories, many traditional 50W applications now require more power to meet new market requirements,” said Patrick Le Fèvre, Marketing and Communication Director of Ericsson Power Modules. “However, many customers prefer to retain previous-generation motherboards and limit upgrades to strategic components, such as processors, memories and power modules. The PKU4619 and PKU4710 meet this need, reducing both cost and time-to-market for developers.”

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

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. In a natural convection environment, full power can be delivered up to +40°C and, with a 3.0m/s airflow,
up to +80°C.

The PKU4619 and PKU4710 are built on Ericsson’s robust power-module platform featuring optimized topology and layout, and use a limited number of components for increased reliability, while also making them extremely cost efficient. Offering an MTBF (Mean-Time-Before-Failure) of more than 3.6 million hours, the PKU4619 and PKU4710 meets safety requirements according to IEC/EN/UL 60950-1, offer input/output isolation of 1500V(dc) with protection features including output-over-voltage protection (OVP), input under-voltage shutdown, over-temperature protection (OTP), and output short circuit protection.

The devices are also available in both through-hole (PI version) and surface-mount (SI version) types.
