XP unveils ‘world’s smallest’ 5 and 10W ac/dc power supplies
XP Power has announced what it believes are the world's smallest 5 and 10W single output ac/dc power supplies.
The 5W ECE05 series measures 25.4 x 25.4 x 15.24mm (1 x 1 x 0.6in) and the 10W ECE10 series measures 38.1 x 25.4 x 15.24mm (1.5 x 1 x 0.6in).
Both series comprise seven models covering nominal output voltages from 3.3 to 48VDC, with a universal input of 85 to 264VAC with Class II construction, meaning no earth or ground connection is required.
A peak load capability permits an output of up to 130% of nominal output power to cater for short term high power loads without the need to specify a higher rated power module, which XP says saves board space and additional cost.
The ECE05/10 modules are convection cooled and are designed to operate without the need for additional heat sinking or forced airflow. Operating temperature is across the range of -25 to 70°C, with no derating until 50°C.
The units meet international IT safety standards EN60950-1, UL609501-1 and CSA22.2 No. 234. They also comply with EN55022 level B limits for conducted and radiated EMC without the need for any additional filtering components.
