HES SERIES - 150 WATT
DESCRIPTION
FEATURES
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.
