The inverter is based on the TL494 integrated circuit. This is a switching regulator that will operate with an input voltage of between 7 and 40 volts DC. This input voltage is supplied to the IC through a reed relay. The reed in normally open. When filament current from a valve radio passes through a [...]
The LA9472A is a 2A monolithic step down switching regulator operating in continuous mode and realized in a new BCD technology allowing the integration of isolated, vertical DMOS power transistors with mixed CMOS/bipolar transistors. The device can deliver 2A at an output voltage adjustable from 5.1V to 40V … Link
Today I leads Switching supply computer Circuit. Come to give friends in see again. By this circuit has can to give electricity pressure 5V 15A,-5V 1A,12V 10A,-12V 1A and have can to give the electric power about 200W. I hope that this circuit may in rows checking meditation repairs a computer has of friends.
