The MINMAX MKWI40 series is the latest generation of high performance DC-DC converter modules setting a new standard concerning power density. The
product offers fully 40W in an encapsulated, shielded metal package with dimensions of just 2.0”x1.0”x0.4”. All models provide ultra-wide 4:1 input voltage
range and precisely regulated output voltages.
Advanced circuit topology provides a very high efficiency up to 90% which allows an operating temperature range of -40°C to +80°C. Further features
include remote On/Off, trimmable output voltage, under-voltage lockout as well as overload and over-temperature protection.
Typical applications for these converters are battery operated equipment, instrumentation, distributed power architectures in communication and industrial
electronics and many other space critical applications.

当今的计算机外部设备，都在追求高速度和高通用性。为了满足用户的需求，以Intel为首的七家公司于1994年推出了USB（Universal Serial Bus，通用串行总线）总线协议，专用于低、中速的计算机外设。目前，USB端口已成为微机主板的标准端口；而在不久的将来，所有的微机外设，包括键盘、鼠标、显示器、打印机、数字相机、扫描仪和游戏柄等等，都将通过USB与主机相连。
