VB408.php - December 11 2011 18:03:39
VB 408 Replacement .:. QO-408 (V1)
The VB408 from SGS Thomson is a versatile High Voltage Regulator IC.
Unfortunately it is no longer produced.
As we used this circuit in a lot of designs like many other users, it
appeared to be a good idea to have a replacement. We therefore designed
a small PCB with a Power Transistor to replace the VB408.
The Design is very sophisticated and the parameters like Output Voltage and
maximum Current may be set by Resistors. See Calculator on the right side ...
Fig. above : the PCB ready to be tested ...
... in the "Demoboard".
With an adequate heatsink, the Power Transistor may dissipate up to 50 W.
