Murata Power Solutions ULS 60W and 100W Isolated DC/DC Converters

Murata Power Solutions ULS 60W and 100W Isolated DC/DC Converters makes another dramatic size shrink down to a “sixteenth brick” width (0.9 inches) while still retaining up to 66W output and full 2250VDC isolation. The PC-board mount converter family accepts 36V to 75V DC inputs and delivers fixed outputs regulated to within ±0.2%. These ULS outputs may be trimmed within ±10% of nominal output while delivering fast settling to current step loads and no adverse effects from higher capacitive loads. These converters with excellent ripple and noise specifications assure compatibility to circuits using CPU’s, ASIC’s, programmable logic and FPGA’s with no minimum load. The ULS series avoid both converter and external circuit hazards including 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. Typical applications include small instruments, computer-based systems, data communications equipment, remote sensor systems, vehicle and portable electronics
