A switch-mode converter from the company is said to provide efficiency up to 97 percent. This provides minimum heat generation that reportedly avoids the physical and mechanical problems associated with heat sinks and waste heat transportation. The R-78 series has a drop-out voltage of 1.5 V and an input voltage range that extends up to 34 V. The R-78xx-0.5 is accommodated in a SIP3-plastic housing measuring 11.5 mm by 7.5 mm by 10.2 mm. The R-78xx-0.5 is continuous short circuit-protected and incorporates a thermal shutdown function that switches off the converter if the internal temperature exceeds 160°C. The operating temperature range is from -40°C to 70°C with full load, and extends from 70°C to 85°C with a derating to 80 percent of maximum load. Mega Electronics Inc., www.megaelectronics.com
