| One of the most frequent uses of n-channel MOSFET’s is as a voltage controlled switch. To ensure that the MOSFET delivers the full supply vo...
| If you thought that an infra-red (IR) controller was only good for zapping TV channels then read on. This novel circuit uses a micro control...
| In early 1984, Elektor magazine beat the competition hands-down by publishing the design of a then-revolutionary MOSFET amplifier. Even now,...
| Pulse width modulation (PWM) is a fundamental technique in electronics. It comes as no surprise, therefore, that there are many applications...
| Most modern handheld transceivers for 2 m and 70 cms ham radio incorporate MOSFET RF power modules and are capable of operating at supply vo...
| It is often desirable to know how hot a part is. The usual method is to use a thermometer to measure the temperature, but this may not alway...
| Transistors are often used for switching power supply voltages. MOSFETs are most often used, since they have low ‘on’ resistances, and they...
| More and more lithium-ion batteries are being used in all kinds of appliances. These require a battery charger and for this Maxim’s MAX745...
| This circuit was originally designed to control the brightness of an electric torchlight, but may find many other applications because o...
