XP Power announced the launch of what it believes to be the world’s smallest 5 and 10 Watt single output AC-DC power supplies. Measuring just 25,4 x 25,4 x 15,24 mm, the miniature 5 Watt ECE05 series of encapsulated board mount power supplies are ideal for end-product designs where the available board space is at a premium and a high power-density supply is required.
Complementing the ECE05 series, the ECE10 series provides 10 Watt output from a similarly compact encapsulated package measuring just 38,1 x 25,4 x 15,24 mm.
Both series comprise seven models covering the popular nominal output voltages from +3,3 to +48 V d.c., all from a wide universal input of 85–264 V a.c. with Class II construction, meaning no earth or ground connection is required.
All models meet the internationally recognised no-load power consumption limit of less than 0,3 Watt and average efficiency limits ensuring end-products can comply with worldwide energy efficiency standards. 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, saving both board space and additional cost.
The ECE05/10 modules are convection cooled and operate without the need for additional heatsinking or forced airflow. Operating temperature is across the range of –25°C 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.
