Description
The MH005-Series Power Modules are dc-dc converters that operate over an input voltage range of 4.5 Vdc to
14 Vdc and provide precisely regulated dc outputs. The outputs are isolated from the inputs, allowing versatile
polarity configurations and grounding connections. The modules have maximum power ratings of 5 W with a
typical full-load efficiency of 73%.
The modules are PC board mountable and encapsulated in nonconductive cases. The modules are rated to full
load at 100 °C case temperature with no external filtering or heat sinking.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute 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 device reliability.

Fusing Considerations
CAUTION: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fus-
ing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The
safety agencies require a normal-blow fuse with a maximum rating of 5 A in series with the input (see Safety Con-
siderations 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 for further
information.

Output Current
* At less than the minimum current, units will continue to operate; however, the single-output modules (MH005A, B, C) may exceed their output
ripple specification. The dual-output modules (MH005BK, CL) may exceed their output voltage regulation limits if the output currents are
severely imbalanced with one output sourcing less than the minimum current.
