Industry Standard Pinout
100°C Case Operation
Short Circuit Protection
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 1500VDC
isolation, short circuit protection, and six-sided shielding.
The LES is available with optional enable and voltage trim
pins. Please see the IAD Series for dual output
applications.
