The most common switching-power topology is a buck converter, which efficiently transforms high voltages to low voltages. Figure 1 shows a typical buck converter in which the N-channel MOSFET, Q 1, ...

An idea in an earlier blog is to make a pwm interface that can accept 5, 12 and 24V pulse streams. That one uses a bunch of resistors and has three separate inputs. Below that, wise commenter DB ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

This circuit transforms a pulse-width-modulation (PWM) signal into non-overlapping clock signals, whose number depends on the length of a shift register. These clock signals can be used to power up ...

Intersil Corp.’s new ISL6227 is a dual PWM controller IC designed to power DDR memory, graphics, chip sets and other systems in notebook PCs. Its wide input voltage range capability allows for voltage ...

I have had an on-going mission to design a universal-ish pcb that will convert a PWM waveform at one frequency into to another frequency while retaining the mark-space ratio. The obvious answer is a ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

The objective is to move a servo motor to a specific location by building a wireless transmitter and a wireless receiver to translate and implement the input data. The objective is to move a servo ...
