Murata Power Solutions recommends a fuse at F1. Typical unit FEATURES Small footprint DC/DC converter, ideal for high current applications Industry standard 0.96" x 1.1" X 0.35" open frame package and pinout Wide range input voltages 9-36 and 18-75 Vdc Bipolar ±5V, ±12V and ±15V outputs Up to 15 Watts or greater total output power with overtemperature shutdown Isolation up to 2250 VDC (basic), Q48 models High efficiency synchronous rectifier forward topology Usable -40 to 85°C temperature range (with derating) Assembly and attachment for RoHS standards Extensive self-protection shut down features Meets UL 60950-1, CAN/CSA- C22.2 No. 60950-1, IEC60950-1, EN60950-1 safety approvals (2nd Edition) Featuring a full 15 Watt output in one square inch of board area, the BEI-15 series isolated DC/ DC converter family offers efficient regulated DC power for printed circuit board mounting. The wide range 4:1 inputs on the 0.96" x 1.1" x 0.35" (24.4 x 27.9 x 8.9 mm) 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. The industry-standard pinout fits larger 1" x 2" converters. Fixed output voltages of ±5, ±12 or ±15 VDC are regulated to within ±0.25%. Applications include small instruments, area- limited microcontrollers, data communications equipment, remote sensor systems, vehicle and portable electronics. The BEI-15 series includes full magnetic and optical isolation with Basic protection up to 2250 Volts DC (Q48 models) and 2000 VDC (Q12 models). For powering digital systems, the outputs offer fast settling to step transients and will accept higher capacitive loads. Excellent ripple and noise specifications assure compatibility to noise-sus- ceptible circuits. For systems requiring controlled startup/shutdown, an external remote On/Off control may use a switch, transistor or digital logic. A wealth of self-protection features avoid both converter and external circuit faults. These include input undervoltage lockout and overtemperature shutdown. The outputs current limit using the “hiccup” autorestart technique and the outputs are short-circuit protected. Additional features include output overvoltage and reverse conduction elimination. The high efficiency offers minimal heat buildup and “no fan” operation.
