Used in a variety of timer, pulse generation, and oscillator applications, the 555 was designed in 1971 by Hans Camenzind. A favorite for many engineers, the 555 is still in widespread use due to its ...

The venerable 555-type timer makes an effective driver for power MOSFETs, but you have to understand the drive situation when selecting the correct variation of the basic timer. This idea shows how ...

Pulse width modulation (PWM) control, which uses variable-width digital pulses to represent the amplitude of an analog waveform, has been around for decades. The first specialized PWM IC dates back to ...
