Ericsson Debuts PKJ 4000 Series Power Modules
Ericsson Microelectronics (Kista, Sweden) announced its 90-percent efficient, fully independent, 110W dual-output half-brick dc/dc power module, the PKJ 4128 PIT. This unit addresses applications requiring 5V and 3.3V outputs. The module offers a low-power loss solution for 48V input applications.
The PKJ 4128 PIT is suitable for a broad range of information technology and telecom applications. The module offers 3.3V and 5V output at 12A/15A, respectively, delivering a total output power of 110W. Each output channel is independent of the other so the user has 110W of power available at any time. The dual-output version includes individually regulated outputs with tight regulation in the same mechanical size as the industry-standard dual half-brick.
Designed using synchronous rectification and patented thermal management techniques, the device features a mean time between failure (MTBF) in excess of three million hours, allowing the PKJ 4000 Series to operate in high ambient temperatures with low airflow and without a heatsink.
The dual half-brick module features over-voltage protection, over-temperature protection, current-limit protection, output-voltage adjust and local on/off, under-voltage detection, remote on/off, and individual output-voltage adjustments.
The PKJ 4000 Series complies with the requirements of EMC specifications such as EN55022 and EN61000, conforms to EN60950 with 1,500Vdc isolation, meets low-voltage directive 73/23/EEC, and carries UL and ULc approvals. The modules are manufactured in ISO9000-approved production facilities and come with a five-year warranty.
The PKJ 4000 Series also includes models with single-output voltages ranging from 1.5V to 12V, at up to 30A output current (150W power limited). Samples are available from stock.
