Ericsson Extends PKL 4000 Series Power Modules
Ericsson Microelectronics (Kista, Sweden) extended its PKL 4000 Series half-brick dc/dc power modules, designed for the wireless telecommunications marketplace, the PKL 4316 PIT. This 310W output power module offers extensive circuit protection and conforms to international safety and EMI regulations.
The 28.2V, 11A PKL 4316 PIT model offers 90 percent efficiency at full power and up to 106.7W per cubic inch. The module is capable of handling input voltages from 36V to 75V.
The hot-pluggable PKL 4000 Series uses the latest circuit topologies, high-reliability components and a low-resistivity PCB to achieve maximum power efficiency and density. The thermal design keeps the output MOSFETs at less than 10 degrees C above the baseplate temperature, contributing to an MTBF of greater than 2.2 million hours.
The industry-standard half-brick format has been enhanced with two additional output pins. All other pin assignments are fully compatible with the industry-standard half-brick pin-out, offering a straightforward route for upgrading existing board designs to take advantage of the new power levels delivered by the 2.4in x 2.4in x 0.5in (61mm x 61mm x 12.5mm) package.
The PKL 4000 Series is short-circuit proof and includes built-in over-voltage, under-voltage and over-temperature protection. It also features soft-start, remote turn-on, output adjustment and remote sensing.
The PKL 4000 Series includes models with output voltages ranging from 1.8V to 12V at up to 60A output current (310W power limited). Samples are available from stock.
