UEI15 Datasheet | Murata Manufacturing

FEATURES n Small footprint DC/DC converter, ideal for high current applications n Industry standard 0.9" x 1.1" X 0.335" open frame package and pinout n Wide range input voltages 9-36 and 18-75 Vdc n Double lead-free assembly and attachment for Ro HS standards n Isolation up to 2250 VDC (basic) n Up to 15 Watts or greater total output power with overtemperature shutdown n High efficiency synchronous rectifier forward topology n Stable no-load operation with no required external ponents n Usable -40 to 85°C temperature range (with derating) n Designed to meet UL 60950-1, CAN/CSAC22.2 No. 60950-1, IEC60950-1, EN60950-1 safety approvals n Extensive self-protection shut down features PRODUCT OVERVIEW Wide range 4:1 inputs on the 0.9" x 1.1" x 0.335" converter are either 9 to 36 Volts DC (Q12 models) or 18 to 75 Volts DC (Q48 models), ideal for batterypowered and tele 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, puter-based systems, data munications 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 patibility 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...
