XWT SERIES - TRIPLE, 150 WATT
Rev. 11/2000
DESCRIPTION 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.
FEATURES • High Power Package • Wide Input Range • 12, 24, and 48V Input Versions • Trim and Enable Pin • Remote Sense Pins • 500V Isolation

Notes
MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load, unless otherwise stated. Soldering Conditions: I/O pins, 260°C, ten seconds; fully compatible with commercial wave-soldering equipment. Safety: Agency approvals may vary from model to model. Please consult factory for specific model information.
