18 to 60V Input Eighth Bricks Provide Full Power at 70°C with Only 200LFM Cooling
Power-One has introduced its EMS Series of 1/8th-brick DC-DC converters. Two single-output models deliver 3.3V @ 15A and 5V @ 10A from an ultra-wide 18 to 60V input range. Efficiencies exceeding 90%, combined with advanced thermal management techniques, facilitate industry-leading 70°C performance; only 200LFM cooling is needed for 5Vout full-power operation with either 24 or 48Vin.
The 18 to 60V input range facilitates operation from 24V and 48V; eliminating the need for multiple host-system circuit-pack designs, and reducing the number of brick part numbers in inventory, in applications such as wireless base stations. Additional features include: RoHS compliancy for all six substances, 1500VDC input-to-output isolation, Basic insulation, start-up into highly-capacitive loads, and low conducted and radiated EMI.
Interface features include: remote on/off, remote output voltage sensing, and industry-standard output trim. Protections include: overvoltage, undervoltage, overcurrent, and overtemperature. Regulatory approvals include: UL60950-1-03/CAN/CSA-C22.2 No. 60950-1, TUV EN 60950-1, and IEC 60950-1. These cost-effective products incorporate 0.43" (10.8mm) heights and industry-standard 2.3 x 0.9 inch (58.4 x 22.9mm) footprints. Pricing is $36 each in quantities of 1000.
