Plug into std 3 terminal regulator TO220 pinout. Similar power specs. Cost unknown (when you find out come back and tell me). http://www.micropowerdirect.com/PDF%20Files/Datasheets/Noniso/SRM7810-Datas= heet.pdf Nothing you couldn't do yourself but it's nu\ice to have it done for you. 90% + efficiency across a lot of the envelope. 5V and 3v3 out versions. SMD DIP like 1 Watt smps http://www.micropowerdirect.com/PDF%20Files/Datasheets/DCDC/LF/LCP100E-Data= sheet.pdf _________________ These converters are specifically designed to replace inefficient linear regulators (LM78xx type) for board level applications that require miniatur= e size, high efficiency, high reliability and low cost. Two standard models operate over an input range of 4.75 to 20 VDC, providin= g tightly regulated outputs of 3.3 or 5 VDC. Output current for all models is 1A. Standard features include efficiency as high as 93%, very low noise operation and tight line/load regulation. All models feature over load protection, over temperature protection and continuous short circuit protection. The MTBF for both models (per MIL HDBK 217F) is greater than 2.= 0 Mhours. The SRM7810 family is packaged in a miniature, Single-Inline-Package (SIP) case that is only 0.45 x 0.30 x 0.40 inches. They feature an industry standard pin-out and all cas= e materials meet UL94-VO. Each model is specified for operation over the wide operating temperature range of -40=B0C to +70=B0C with no derating or heat sinking required (dera= ted operation to +85=B0C is specified). Cooling is by free-air convection. The SRM7810 series offers an ideal combination of miniature size, robust performance and low cost. They are an ideal replacement for inefficient linear POL regulators (which typically need heat sinking and/or airflow), providing reliable operation over a wide operating temperature range withou= t any need of external heat sinking or board layout changes. Applications would include industrial process systems, remote or battery backed systems, test/lab instrumentation, robotic systems and board level power distributio= n subsystems. *MicroPower Direct** *products are designed to provide long, reliable field life. Considerable attention is given to the proper selection, derating, an= d layout of all circuit components. In addition, extensive reliability screening is also performed on all modules as a routine part of our production process. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
