Description
The JRCW450R Orca series of dc-dc converters are a new generation of isolated, very high efficiency DC/DC power modules
providing up to 450W output power 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 feature, 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.
