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.
