Description
The JNW350R series of dc-dc converters are a new generation of isolated DC/DC power modules providing up to
350W output power in an industry standard 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 LoopTM, 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.
