In LCD backlight applications, a dc-to-ac inverter drives cold-cathode fluorescent lamps. The inverter's input comes from the display's power supply. Currently, it spans from 12 to 18 V. Pulse-width ...

In IC design, the typical approach for generating a pulse width-modulated (PWM) signal from an analog value (such as in the control loop for a switch mode power supply) uses a ramp or triangle wave ...

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...

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 ...

Linear Technology has unveiled a new pulse width modulation (pwm) generator with 48 independent channels. According to the IC specialist, each channel has an individually adjustable 12bit (4,096 steps ...

Renewable energy continues to be a massive trend around the world. As methods for capturing wind, solar, and other forms of renewable energy have developed, the cost and efficiency of renewable energy ...

One way around the problem of getting a fast response from a microcontroller is to move the problem away from the processor. In the case of the ESP32 there are some built-in devices that can use GPIO ...
