ELECTRONICS: MicroPower Direct’s MPM-03S series is a family of single output, 3W switching power supplies. These low-cost modules include a universal ac input, full safety approvals, robust filtering and miniature DIP packaging. Six standard models operate from a universal input of 85 to 264V ac; providing tightly regulated single outputs of 3.3, 5, 9, 12, 15 or 24V dc. Standard features include universal 85 to 264V ac inputs, filtering to EN55022, input/output isolation of 3,000V ac and very low leakage current. All models are protected for over temperature and short-circuit faults. The MPM-03S has a Class II input (IEC61140). This means it can be used without an earth ground connection. The series, which is RoHS compliant, is packaged in an ultra-miniature DIP package. Each model is specified for operation over the wide operating temperature range of -25 to 71C (ambient).
The fun factor continues to draw developers to Linux. This open-source system continues to succeed in the market and in the hearts and minds of developers. Design News will delve into this territory with next week's Continuing Education Class titled, “Introduction to Linux Device Drivers.”
