Murata today announced the MEE1 series, a 1-Watt single output PCB mounted DC-DC converter designed for a broad range of industrial, automation, and instrumentation applications that require an isolated low-power distributed supply. These highly efficient converters, ? up to 86%, are available in a variety of models accommodating the popular nominal input voltages of 3.3, 5, 12, 15, or 24 V DC and with output voltages of 3.3, 5, 9, 12, or 15 V DC. Compared to similar sized and power rated products currently available on the market, the MEE1 efficiency has increased by up to 8% and has a typical efficiency range of 76 - 86% depending on output voltage. Load regulation has also significantly improved and is now as low as 3% across the load rate of 10 to 100% for the 24 V DC input/15 V DC output model, MEE1S2415SC. Isolation is 1 kV DC. The MEE1 converter series is available in the industry standard SIP 4-pin and DIP 8-pin formats, giving designers a choice of package depending on the space available within their end product. The MEE1 is a pin-compatible drop-in replacement for updating older designs without the need for any PCB changes. The MEE1's isolation allows configuring the converter to provide an isolated negative rail in systems where only a positive rail exists. Safety certification to the internationally recognized UL60950 specification is currently pending. The series can operate at full output power across a wide range of temperatures from -40 to +85 °C making it suitable for use in most operating environments. Murata
