LES SERIES - 15 WATT
DESCRIPTION
LES DC/DC converters provide up to 15 Watts of output
power in an industry standard package and footprint. With
a maximum case temperature of 100°C, the LES is well
suited for the most demanding telecom, networking, and
industrial applications. The LES features 1500 VDC
isolation, short circuit, and overtemperature protection, as
well as six-sided shielding. The LES is available with
optional enable and voltage trim pins. Please see the IAD
Series for dual output applications.
