DESCRIPTION
The VB408, VB408B, VB408FI are fully protected
positive adjustable voltage regulators made using a
proprietary High Voltage VIPower
technology. The
device can beconnected toa D.C. source (upto 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 V
IN
-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.
