HES DC-DC Series Data Sheet
Half-Brick Converters
Description
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 specifications, 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.

Notes
† MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load, unless
otherwise stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully
compatible with commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model. Please
consult factory for specific model information.
Units are water-washable and fully compatible with commercial spray
or immersion post wave-solder washing equipment.
