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.

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.
