DC/DC Product Specification
- Half brick fully regulated DCDC converter.
Product De s c ription
The AGH100-48S3V3 is the latest high efficiency half brick. It operates from a
wide input range of 36Vdc to 75Vdc and provides a regulated output voltage of
3.3Vdc. The output is rated to a power level up to 82.5Watts .Its protection
features include Non latching OCP , OTP and OVP. It also has an enable pin on
the primary side of the converter. The unit is a baseplate design that is optimised
for either contact-cooled ap plications or forced airflow applications.
