VEFT1-S5-S12-SMT

rev. page date 1 of 3 10/2009 PART NUMBER: VEFT1-SMT DESCRIPTION: single output series dc-dc converter Description Designed to convert fixed voltages into an isolated voltage, the VEFT1-SMT single 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. Features ·Isolated 1 W output ·Temperature range: -40°C~+85°C ·Unregulated ·High efficiency to 80% ·Single voltage output ·Small footprint ·SMD package style ·Industry standard pinout ·UL94-V0 package ·No heatsink required ·3K Vdc isolation ·Power density 0.85 W/cm³ ·No external component required ·Low cost Output Voltage 3.3 Vdc 5 Vdc 3.3 Vdc 5 Vdc 9 Vdc 12 Vdc 15 Vdc 24 Vdc 3.3 Vdc 5 Vdc 9 Vdc 12 Vdc 15 Vdc 24 Vdc 3.3 Vdc 5 Vdc 9 Vdc 12 Vdc 15 Vdc 24 Vdc Output Current Package Max.
