LES SERIES - 15 WATT DESCRIPTION FEATURES 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. • • • • Industry Standard Package Industry Standard Pinout 85°C Case Operation Short Circuit Protection • 24V and 48V Inputs • Input Pi Filter and 6-Sided Shielding • Regulated Outputs • 1500V Isolation Efficiency vs. Load (24V Input) 85 80 EFFICIENCY % 75 TECHNICAL SPECIFICATIONS 70 LES010YE-A 65 EFF.
