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.
