Description
The JHW250-series dc-dc converters are a new generation of DC/DC power modules designed for
maximum efficiency and power density. The JHW series provide up to 250W 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 typically 92% at 30.2V with full load. The 5-sided encapsulated case
package allows for excellent thermal performance in strict thermal environment. Threaded or non-
threaded-through holes are provided to allow easy mounting to a cold wall or addition of a heatsink for
high-temperature applications. The JHW250 series power modules are isolated dc-dc converters that
operate over a wide input voltage range of 36 to 75 Vdc 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.
