VEFT1-S12-D9-SMT

1/3 VEFT1-SMT Dual Output Series Dc-Dc Converter Rev. 11-2005 Description Designed to convert fixed voltages into an isolated voltage, the VEFT1-SMT dual series is well suited for providing board-mount local supplies in a wide range of applications, including mixed analog/digital circuits, test & measurement equip., process/machine controls, datacom/telecom fields, etc... The semi-regulated output can be followed by 3-terminal regulators to provide output protection, in addition to output regulation.
