FEATURES ►High Power Density in SIP-8 Package ►Small Footprint: 21.8 x 9.3 mm (0.86”x 0.37”) ►Ultra-wide 4:1 Input Ranges ►Fully regulated Output ►Operating Temp. Range –40° to +90°C ►Overload Protection ►I/O-isolation 1500 VDC ►Remote On/Off Control ►3 Years Product Warranty PRODUCT OVERVIEW The MCWI02 series is a range of isolated 2W DC/DC converter modules featuring fully regulated output and ultra-wide 4:1 input voltage ranges. The product comes in a SIP-8 package with a very small footprint occupying only 2.0 cm2 (0.32 square in.) on the PCB. An excellent efficiency allows an operating temperature range up to 75°C at full load. Further features include remote On/Off control and over load protection. The very compact dimensions of these DC/DC converters make them an ideal solution for many space critical applications in battery-powered equipment and instrumentation.
