HBS50 DC-DC Series Data Sheet
50-Watt Half-Brick
EFFICIENCY %
Description
HBS dc-dc converters provide up to 50 watts of output
power in an industry-standard, half-brick footprint. The
HBS units feature excellent efficiency, Class A conducted
noise specs, and fixed switching frequency. The HBS,
using open-frame packaging, along with planar magnetics
provides maximum useable power with minimal thermal
constraints. The HBS Series is especially suited to
telecom, networking, and industrial applications.
Features
• RoHS lead solder exemption compliant
• Industry-standard half-brick
• Open-frame packaging
• 100 °C base plate operation
• Water washable
• “True-trim” option
• 1500 V isolation
• Positive or negative logic

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.
