TECHNICAL SPECIFICATIONS

HES single output DC/DC converters provide up to

150 Watts of output power in an industry standard,

half-brick package and footprint. These units feature

ultra-high efficiency, Class A conducted noise specs,

and fixed switching frequency. The HES is designed

with open-frame packaging, along with planar

magnetics to provide maximum useable power with

minimal thermal constraints. The HES is especially

suited to harsh telecom, networking, and industrial

applications, and is fully compatible with production

board washing processes.
