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. TTypical unitypical unit FEATURES PRODUCT OVERVIEW Small footprint DC/DC converter, ideal for high Wide range 4:1 inputs on the 0.92 x 1.92 x 0.35 programmable logic and FPGAs. No minimum current applications converter are either 9 to 36 Volts DC (Q12 models) load is required. For systems requiring controlled 0.92 x 1.92 x 0.35 open frame package or 18 to 75 Volts DC (Q48 models), ideal for startup/shutdown, an external switch, transistor battery-powered and telecom equipment. Fixed or digital logic may be used to activate the remote Wide range input voltages 9-36 and 18-75Vdc output voltages from 3.3 VDC to 15 VDC are tightly On/Off control. Assembly and attachment for RoHS-6 hazardous regulated and may be trimmed within 10% A wealth of self-protection features avoid both substance compliance of nominal output. Applications include small converter and external circuit problems. These Isolation up to 2250 VDC (basic), Q48 models instruments, computer-based systems, data com- include input undervoltage lockout and overtem- Up to 30W total output power with munications equipment, remote sensor systems, perature shutdown. The outputs current limit using overtemperature shutdown vehicle and portable electronics. the hiccup autorestart technique and the outputs High ef ciency synchronous recti er forward The UEI 30W Series includes full magnetic may be short-circuited inde nitely. Additional topology and optical isolation up to 2250 Volts DC (basic features include output overvoltage and reverse insulation), Q48 models. For connection to digital conduction elimination. Stable no-load operation with no required systems, the outputs offer fast settling to current external components The synchronous recti er forward topology step loads and tolerance of higher capacitive offers high ef ciency for minimal heat buildup 40 to +85C temperature range see derating loads. Excellent ripple and noise speci cations and no fan operation.
