PART NUMBER: VBT1-SMT
DESCRIPTION: dc-dc converter
description
Designed to convert fixed voltages into an isolated voltage, the VBT1-SMT 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.
