Description

The KHHD006A0A series power modules are isolated DOSA compliant 1/16th brick dc-dc converters that operate over an ultrawide input voltage range of 18 V

-75Vdc and provide a single precisely regulated output voltage at 5.0Vdc. The output is fully

isolated from the input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency of 90% typical at full load. Built-in filtering for both input and output minimizes the need for external filtering. The module is fully self-protected with output over-current and over-voltage, over-temperature and input under voltage shutdown control. Optional features include negative or positive on/off logic and SMT connections.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.

CAUTION: This power module is not internally fused. An input line fuse must always be used.

This power module can be used in a wide variety of applications, ranging from simple standalone operation to being part of complex power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 5A. (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.
