UEI15-033-Q48PML1-C

www.murata-ps.com Typical unit UEI15 Series Isolated Wide Input Range 15-Watt DC/DC Converters Featuring a full 15 Watt or greater output in one square inch of board area, the UEI series isolated DC/DC converter family offers efficient regulated DC power for printed circuit board mounting. FEATURES „ Small footprint DC/DC converter, ideal for high current applications „ Industry standard 0.96" x 1.1" X 0.32" open frame package and pinout „ Wide range input voltages 9-36 and 18-75 Vdc „ Assembly and attachment for RoHS standards „ Isolation up to 2250 VDC (basic) „ Up to 15 Watts or greater total output power with overtemperature shutdown „ High efficiency synchronous rectifier forward topology „ Stable operation with no required external components „ Usable -40 to 85°C temperature range (with derating) „ Certified to UL 60950-1, CAN/CSA-C22.2 No. 60950-1, IEC60950-1, EN60950-1 safety approvals, 2nd edition „ Extensive self-protection shut down features PRODUCT OVERVIEW Wide range 4:1 inputs on the 0.96" x 1.1" x 0.32" converter are either 9 to 36 Volts DC (Q12 models) or 18 to 75 Volts DC (Q48 models), ideal for batterypowered and telecom equipment. The industrystandard pinout fits larger 1" x 2" converters. Fixed output voltages from 3.3 VDC to 15 VDC are regulated to within ±0.2% or less and may be trimmed within ±10% of nominal output. Applications include small instruments, area-limited microcontrollers, computer-based systems, data communications equipment, remote sensor systems, vehicle and portable electronics. The UEI 15W series includes full magnetic and optical isolation up to 2250 Volts DC (basic insulation). 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, programmable logic and FPGA’s. 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 high efficiency offers minimal heat buildup and “no fan” operation. +VOUT +VIN –VOUT On/Off Control Control GATE DRIVE ISOLATION BARRIER −VIN ISOLATION Reference, Trim & Error Amplifier TRIM Figure 1.
