ROF-78E DC/DC Power Modules

RECOM's ROF-78E series are non-isolated, DC/DC power modules


RECOM's ROF-78E series high-efficiency switching regulators are ideally suited to replace SMD linear regulators. The ROF-78E is a low profile, postage-stamp-sized SMD DC/DC power supply module designed to provide 5 V or 3.3 V at up to 0.5 A continuous load (0.95 A peak). It is also short circuit, overload and over-temperature protected. An enable connection is provided to allow sequential start-up and shutdown control. The modules small footprint of 12.5 mm x 13.5 mm and a height of only 4.5 mm will find many applications in low-profile PCBs, rack-mounted cards and restricted space designs. The high efficiency of up to 87% means that no heatsinks or forced cooling is required to meet the -40°C to +75°C ambient temperature range (no derating). Despite its low cost, the ROF-78E is subjected to the same rigorous RECOM quality checks as all other SMD products and carries the same three-year warranty. RECOM's ROF-78E Power Modules
