Figure 1 shows the typical circuits. Figure 1 Traditional active clamp circuit for PSFB synchronous rectifier MOSFETs. Source: Texas Instruments. In this schematic, you can see the P-channel ...

Abstract: In this brief, a low-overhead circuit technique is proposed to simultaneously reduce subthreshold and gate-oxide leakage currents in domino logic circuits. pMOS sleep transistors and a dual ...

Mouser Electronics, Inc. announced the availability of SSL5015TE/1Y (771-SSL5015TE/1Y) LED Driver integrated circuits featuring highly integrated switch mode LED driver and an integrated circuit ...

If you use a standard bulb it behaves as the "medium" circuit, so you get the off-off-on-on behavior. You can get 3-way LED bulbs that have two independent circuits, but they cost more.

The 1uF keeps the long button press from keeping the PMOS on as in other circuits. I have no idea why the test circuit wouldn’t work. Button bounce shouldn’t matter.

The arduino Uno expects a 8x8 LED input with PMOS transistors connecting to a 5V source and resistors (80 Ohm) connecting to ground. The program consumes an 8x8 array representing the starting point ...

An optional diode on LED − protects against LED-to-GND short-circuits. The 2-MHz converter in Figure 3 features 85% efficiency (87% without EMI filters) at 12-V V IN , 15-V V LED , 330-mA I LED ...

Programmable LED Indicator circuit. Switch S2 is included for resetting the circuit. Instead of just one bicolour LED you can use an array of bicolour LEDs in conjunction with two driver transistors. ...
