Description
The JNCW016A0R ORCA series of dc-dc converters are a new generation of isolated, very high efficiency DC/DC power modules
providing up to up to 16Adc output current at a nominal output voltage of 28Vdc in an industry standard, DOSA compliant half-
brick size footprint, which makes it an ideal choice for high voltage and high power applications. Threaded-through holes are
provided to allow easy mounting or addition of a heatsink for high-temperature applications. The output is fully isolated from the
input, allowing versatile polarity configurations and grounding connections. This module contains an optional new capability, the
Tunable Loop, that allows the user to optimize the dynamic response of the converter to match the load with reduced amount of
output capacitance, leading to savings on cost and PWB area.

Absolute Maximum Ratings
Data Sheet
JNCW016A0R Orca Series; DC-DC Converter Power Modules
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 an integrated
part of complex power architecture. To preserve maximum flexibility, internal fusing is not included. Always use an input line fuse,
to achieve maximum safety and system protection. The safety agencies require a time-delay or fast-acting fuse with a maximum
rating of 25 A in the ungrounded input connection (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.
