200W converter cuts board space by 40%
The PKU4300D series delivers the highest power and highest efficiency in the industry for a one-sixteenth-brick footprint DC/DC module for istributed and intermediate bus applications in ICT, telecom and industrial markets. Contract manufacturer Flex bought Ericsson’s power module business in June 2017 and launched its first module as a result in December.
The new converter has a wide 36V to 75V DC input range, delivers a tightly regulated 12V output, and handles up to 204W in power. Other modules available in the PKU4300D family include a 135W version that has a 5V output at 27A, and a 100W version that offers a 3.3V output at 30.3A.
The module is ideal for use in distributed power and intermediate bus voltage architectures within the Information and Communication Technology (ICT), telecom and industrial sectors. It also targets deployment in high-power and high-performance use in applications that are powered by multi-cell batteries or rectifiers and meets all the requirements for use in products such as networking and telecommunications equipment, servers and data storage applications, as well as industrial equipment.
The module’s efficiency of up to 95% with a 48V input for telecommunications and data communications sectors can deliver significant reductions in energy and cooling costs for end users. In addition, the module’s high-end performance in challenging thermal environments means higher useable power in applications that are designed to operate in high ambient temperature and limited airflow environments, thereby providing higher product reliability.
The converter uses the industry-standard DOSA-compatible five-pin one-sixteenth-brick package with dimensions of 33.02 x 22.86 x 11.30mm,and can either be through-hole or surface mounted, for maximum flexibility at the board assembly stage. The module is also available as an open frame unit, where it delivers 180W at the 12V output, or with a baseplate, delivering its full output power capability of 204W.
The PKU4213D’s input-to-output (I/O) isolation voltage of 2250V DC also enables it to be used in a wide range of applications, including Power over Ethernet (PoE). In addition, advanced protection features of the module include output-over-voltage, over-temperature and over-current.
