Backup Battery Control Circuit

| 2008/09/01

For control in the backup battery controller circuit, L4949, 4093B integrateds are used, the status of the main battery is checked and when necessary, the backup battery is activated via the 80 amp relay – Control Circuit for L4949 4093B and Backup Battery 12/24V Auxiliary Battery Controller It is common practice to add a second…

3A 5V Switching Regulator

| 2008/08/26

The regulator circuit with mosfet has a simple structure and can provide 5v 3 amps at the output with 24v input voltage. The author warned that the input voltage should not be below 11v. Switching regulator with 5V 3A mosfet Super simple regulator works very well but is it possible to improve it? Maybe with…

555 Stepper Motor Driver Circuit

| 2008/08/25

Circuit made ​​a long time ago and has been tested. There were a problem in the operation and construction. We must do BDX53 your engine is larger output transistors. 5 and 6 pin motors can be run with the circuit. Four-ended output transistor to run the engine to be increased. So four BC327 should be…

Switching Regulator LM2575T-ADJ DC to DC Converter Circuit

| 2008/08/18

Now bring the involvement of voltage stabilizer with much greater efficiency, which will not significantly alter the value of the input voltage. step down converter. It is a source of switching, the so-called step down converter. Many manufacturers have already produced a special integrated circuits, which brings together budic, power transistor and feedback controls output…
