XWT SERIES - TRIPLE, 150 WATT
XWT DC/DC converters are high power, triple output
converters that cover a wide range of applications. The
XWT features remote sense leads for accurate point of
load regulation, and has short circuit and overcurrent
protection. For single and dual output high power
solutions, see the XWS and XWD series.
