The PKJ4000 series delivers 28V DC or 50V DC at up to 700W of power from an input voltage range of 36V to 75V.
Packaged in the industry-standard, half-brick format, measuring 2.40 x 2.28 x 0.50 inches, the PKJ4000 achieves a power density of more than 255W/in3.
Conduction cooling of the module is said to be optimised via the attached baseplate, which enables full power delivery at up to 85°C ambient, with a 100°C baseplate temperature and zero airflow in closed-box environments.
Two models are initially available at release. The PKJ4716APIHS delivers 28V at up to 25A/700W, with an output voltage adjustment range of 14V to 35V, while the PKJ4716HPIHS delivers 50V at up to 14A/700W, adjustable from 25V to 55V.
The range of adjustability of the outputs makes them not only suitable for RFPA applications using LDMOS or GaN transistor technology, but also for other applications and markets that require a regulated programmable bus voltage, such as 24V, 28V, 32V, 48V, 50V or 53/54V, Test and Automation, and Industrial Control and Instrumentation.
Other product features of the PKJ4000 series include 1500V input/output isolation, basic level insulation, monotonic start-up, remote sensing, remote control, and a range of protection capabilities including over-temperature, output-short-circuit and output-over-voltage.
