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...

1-05-2003 | This short article will deal with testing power MOSFETs using an ordinary digital multimeter. Anybody who have ever tried this must have mar...

1-12-2001 | If you have an application in which a MOSFET is already used to switch a load, it is relatively easy to add short-circuit or overload protec...

1-11-2001 | In designing a product that is powered from the mains, there are various factors that ultimately determine the choice of power supply. Incre...
