Ericsson PKM4515ZE PI, PKM4619E PI, and PKM4810E PI: Quarter-brick, dc/dc-power modules claim 92% typical efficiency

Available in a quarter-brick format, the PKM4515ZE PI, PKM4619E PI, PKM4810E PI dc/dc modules provide a 48V input voltage. The PKM4515ZE PI runs at 24V at 2.1A and provides a 50W output; the PKM4619E PI runs at 2.5V at 25A and provides a 62.5W output; and the PKM4810E PI runs at 3.3V at 25A and provides an 80.5W output. Typically operating at 92%, the devices run at a 3.3V output voltage at half-load and operate at a 36 to 75V-dc input-voltage range. Providing 1.5 million hours MTBF at 40°C, the PKM4515ZE PI costs $21.46, and the PKM4619E PI and PKM4810E PI cost $24.68.
