VBT2-SMT

1/3 VBT2-SMT Series DC-DC Converter Rev. 12-2006 Description Designed to convert fixed voltages into an isolated voltage, the VBT2-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. Features ·Isolated 2 W output ·Temperature range: -40°C~+85°C ·Unregulated ·High efficiency to 85% ·Single voltage output ·Small footprint ·SMT package style ·Industry standard pinout ·UL94-V0 package ·No heatsink required ·1K VDC isolation ·High power density ·No external component required ·Low cost Model Number VBT2-S5-S5-SMT VBT2-S5-S9-SMT VBT2-S5-S12-SMT VBT2-S5-S15-SMT VBT2-S12-S5-SMT VBT2-S12-S9-SMT VBT2-S12-S12-SMT VBT2-S12-S15-SMT Input Voltage Nominal 5 Vdc 5 Vdc 5 Vdc 5 Vdc 12 Vdc 12 Vdc 12 Vdc 12 Vdc Range 4.5~5.5 Vdc 4.5~5.5 Vdc 4.5~5.5 Vdc 4.5~5.5 Vdc 10.8~13.2 Vdc 10.8~13.2 Vdc 10.8~13.2 Vdc 10.8~13.2 Vdc Output Voltage 5 Vdc 9 Vdc 12 Vdc 15 Vdc 5 Vdc 9 Vdc 12 Vdc 15 Vdc Output Current Max. 400 mA 222 mA 167 mA 133 mA 400 mA 222 mA 167 mA 133 mA Min. 40 mA 23 mA 17 mA 14 mA 40 mA 23 mA 17 mA 14 mA Efficiency 81% 82% 84% 84% 82% 83% 85% 85% Package Style SMT SMT SMT SMT SMT SMT SMT SMT Output Specifications Item Output power Line Regulation Load Regulation Test conditions For Vin change of 1% 10% to 100% full load (3.3V,5V output) 10% to 100% full load (9V output) 10% to 100% full load (12V output) 10% to 100% full load (15V output) See tolerance envelope graph 100% load 20 MHz Bandwidth Full load, nominal input Min. 0.2 Typ.
