Description
The JRW series provide up to 70A output current in an industry standard half brick, which makes it an ideal choice
for optimum space, high current and low voltage applications. The converter incorporates synchronous rectification
technology and innovative packaging techniques to achieve high efficiency reaching 91% at 3.3V full load. The ultra
high efficiency of this converter leads to lower power dissipation such that for most applications a heat sink is not
required. 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.
