DC/DC Product Specification - 1/8th brick fully regulated DCDC converter. Rev 09/07/2012 AVO100B series Page 1 of 2 AVO100B-48S3V3 1/8th brick Input voltage: 36-75V Single Output: 3.3V Rated power: 99W Product Description th The AVO100B-48S3V3 is the latest high efficiency 1/8 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. Special Features -2:1 Wide input range -Optimised for High density, small space applications -Low ripple and noise -Fixed switching frequency -High efficiency -High capacitive load capability -Basic insulation system -Through hole termination - Open frame structure with Base-plate option Specifications Feature Output power: Super high efficiency: Functions: Insulation: Safety UL: TUV/CE: Input specification Input range Input Surge Control specification Enable Output specification Output Voltage Trim range Output Current Ripple and noise Regulation Switching Frequency Isolation Voltage Transient response. 99W 92%(3.3V) Remote control, trim function, Sense; Input LVP, output OVP and OCP, OTP Open frame structure with base plate option.
