VBT2-S12-S15-SMT

rev. rev. page date 1 of 3 02/2008 PART NUMBER: VBT2-SMT series DESCRIPTION: dc-dc converter 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 ·SMD package style ·industry standard pinout ·UL94-V0 package ·no heatsink required ·1K Vdc isolation ·high power density ·no external component required ·low cost m odel n umber 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. min. 400 mA 40 mA 222 mA 23 mA 167 mA 17 mA 133 mA 14 mA 400 mA 40 mA 222 mA 23 mA 167 mA 17 mA 133 mA 14 mA efficiency 80% 82% 84% 84% 82% 83% 85% 85% OUTPUT SPECIFICATIONS item output power line regulation load regulation test conditions for Vin change of 1% 10% to 100% full load (5 output) 10% to 100% full load (9 output) 10% to 100% full load (12 output) 10% to 100% full load (15 output) see tolerance envelope graph @ 100% load 20 MHz bandwidth full load, nominal input min. 0.2 typ. max. 2 ±1.2 15 15 15 15 0.03 150 units W % % % % % %/°C mVp-p KHz 12.8 8.3 6.8 6.3 output voltage accuracy temperature drift output ripple switching frequency 75 70 NOTE: 1.
