muRata IRS-5/10-Q12PF-C

Optimized for harsh environments in industrial/railway applications, the IRS DC-DC converter series offer regulated outputs in an industry-standard sixteenth-brick fully encased package. The IRS series makes another dramatic size shrink down to a “sixteenth brick” width (1.04 inches) while still retaining a high power output and full 2828 Volt DC isolation. The converter family accepts 9 to 36 Volts DC inputs and delivers fixed outputs regulated up to within ±0.125%. The IRS converters are ideal for industrial and railway applications, datacom and telecom applications, cell phone towers, data centers, server farms and network repeaters. IRS outputs may be trimmed while delivering fast settling to current step loads and no adverse effects from higher capacitive loads. Excellent ripple and noise specifications assure compatibility to circuits using CPU’s, ASIC’s, programmable logic and FPGA’s. No minimum load is required. For systems requiring controlled startup/shutdown, an external remote On/Off control may use a switch, transistor or digital logic. Many self-protection features on the IRS series avoid both converter and external circuit hazards. These include input undervoltage shutdown and overtemperature shutdown. The output of these DC-DC converters have 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 synchronous flyback topology yields high efficiency for minimal heat buildup and “no fan” operation.
