Description

The VB408, VB408B, VB408FI are fully protected positive adjustable voltage regulators made using a proprietary High Voltage VIPower] technology. The  VB408, VB408B, VB408FI devices can be connected to a D.C. source (up to 400V) or in off-line application directly to the rectified main (110V/230V). It is particularly suitable to be used in the manufacture of DC/DC converters, AC/DC converters,start-up circuits, pneumatic valve drivers and current sources. The device is able to drive resistive or inductive loads with an output voltage from 1.25V to VIN-30V providing an internally limited output current; it has built in short circuit and thermal shutdown protections. The device does not provide galvanic insulation from main.
