仕様・特性

UEI30 Series www.murata-ps.com 30W Isolated Wide-Range DC-DC Converters Featuring a full 30 Watt output in 1.8 square inches of board area, the UEI series isolated DC/DC converter family offers efficient regulated DC power for printed circuit board mounting. Typical unit FEATURES PRODUCT OVERVIEW  Small footprint DC/DC converter, ideal for high current applications  0.92" x 1.92" x 0.35" open frame package  range input voltages 9-36 and 18-75Vdc Wide  Assembly and attachment for RoHS-6 hazardous substance compliance  Isolation up to 2250 VDC (basic), Q48 models  to 30W total output power with Up overtemperature shutdown  efficiency synchronous rectifier forward High topology  Stable no-load operation with no required external components  to +85°C temperature range; see derating –40  ed to UL60950-1, CSA-C22.2 No. 234 Certifi safety approvals, and CE marking on 48V input only  Extensive self-protection shut down features Wide range 4:1 inputs on the 0.92" x 1.92" x 0.35" converter are either 9 to 36 Volts DC (Q12 models) or 18 to 75 Volts DC (Q48 models), ideal for battery-powered and telecom equipment. Fixed output voltages from 3.3 VDC to 15 VDC are tightly regulated and may be trimmed within ±10% of nominal output. Applications include small instruments, computer-based systems, data communications equipment, remote sensor systems, vehicle and portable electronics. programmable logic and FPGA’s. No minimum load is required. For systems requiring controlled startup/shutdown, an external switch, transistor or digital logic may be used to activate the remote On/Off control. A wealth of self-protection features avoid both converter and external circuit problems. These include input undervoltage lockout and overtemperature shutdown. The outputs current limit using the “hiccup” autorestart technique and the outputs may be short-circuited indefinitely. Additional features include output overvoltage and reverse conduction elimination. The UEI 30W Series includes full magnetic and optical isolation up to 2250 Volts DC (basic insulation), Q48 models. For connection to digital systems, the outputs offer fast settling to current step loads and tolerance of higher capacitive loads. Excellent ripple and noise specifications assure compatibility to circuits using CPU’s, ASIC’s, The synchronous rectifier forward topology offers high efficiency for minimal heat buildup and “no fan” operation.
