More about MOSFET (125)

1-12-2006 | Out of curiosity I delved into the Elektor relics cabinet and pulled out an almost intact example of the 20/80 m SSB receiver we published i...

1-07-2006 | The debate still goes on as to which are better, valves or transistors. We don't intend to get involved in that argument here. But if y...

1-07-2006 | The MAX1562 is a purpose-built USB current limiter from the chip manufacturers Maxim. The device operates with a supply voltage from 4.0 to...

1-07-2006 | The TPS6420x controller is designed to operate from one to three series-connected cells or from a 3.3 V or 5 V supply obtained from a USB po...

1-07-2006 | The losses in a bridge rectifier can easily become significant when low voltages are being rectified. The voltage drop across the bridge is...

1-12-2004 | This circuit shows that dimmers intended for use at mains voltage do not always have to contain a triac. Here, a MOSFET (BUZ41A, 500 V/4.5A)...

1-10-2004 | As already mentioned in the previous parts of this article, this final amp needs more than just a heavy-duty symmetrical power supply. In th...

1-07-2004 | If you ever thought of experimenting with pulse-width modulation, this circuit should get you started nicely. We’ve kept simplicity in mind...

1-12-2003 | The precision current sink shown in Figure 1, which uses a Si4936 DY dual MOSFET (IC1) as a controlled load resistance, is very energy-effic...

1-07-2003 | When a sensitive circuit must under no circumstances have too high a supply voltage applied, then some means of disconnecting the supply mus...
