The JHC/JHW-series dc-dc converters are a new generation of DC/DC power modules designed for maximum
efficiency and power density. The JHC/JHW series provide up to 350W output power in an industry standard Half-
brick, which makes it an ideal choice for high voltage and high power applications. The converter incorporates
synchronous rectification technology and innovative packaging techniques to achieve ultra high efficiency reaching
93.5% at 28V with full load. The 5-sided encapsulated case package allows for excellent thermal performance in
strict thermal environment. Threaded-through holes are provided to allow easy mounting or addition of a heatsink for
high-temperature applications. The JHC/JHW series power modules are isolated dc-dc converters that operate over
a wide input voltage range of 18 to 36 Vdc or 36 to 75 Vdc respectively and provide single precisely regulated
output. The output is fully isolated from the input, allowing versatile polarity configurations and grounding
connections. Built-in filtering for both input and output minimizes the need for external filtering.
