DC/DC Product Specification - 1/8th brick fully regulated DCDC converter. Product Description The AVO100B-48S3V3 is the latest high efficiency 1/8th 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 99Watts maximum. 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 an open frame design with base-plate option that is optimised for either contact-cooled applications or forced airflow applications. Specifications Feature Output power: 99W Super high efficiency: 92%(3.3V) Functions: Remote control, trim function, Sense; Input LVP, output OVP and OCP, OTP Open frame structure with base plate option.
