DC/DC Converter TMA Series, 1 Watt Industry standard pinout Non-regulated output Single and dual output models I/O isolation voltage 1000VDC High efficiency The TMA series are miniature, isolated 1 W DC/DC-converters in a Sin- Operating temperature range 40 C to gle-in-Line package (SIP). Requiring only 1.2 cm2 board space they offer the +85 C ideal solution in many space critical applications for board level power distribu- tion. The use of SMD technology makes it possible to offer a product with high performance at low cost. Models Order Code Input Voltage Output 1 Output 2 Efficiency Range Vnom Imax Vnom Imax typ.
