Description
The HHS60 Series of high-density, single-output dc-dc converters is ideal for telecom and datacom systems that
require low voltage at high current in an industry-standard, half-brick footprint. Highly efficient topology and
thermally-optimized construction allow the units to provide high output current in the system over a wide operating
temperature range while still maintaining a safe guardband for component electrical and thermal ratings. The
addition of an external heat sink increases the capacity of the unit. The HHS60 employs 100% surface-mount
components for consistency and reliability in our production process, and is available in four standard output
voltages from 1.5 to 3.3 VDC.
