ZMDI introduces an addition to the ZSPM15xx series, the ZSPM1509, a true-digital PWM controller IC designed for applications in networking, communications, and industrial applications. The device is ...

A motor-drive servo amplifier's output voltage has a fundamental frequency and amplitude that corresponds to the motor speed, torque, and number of motor poles. PWM amplifiers, by their nature, also ...

This article describes a simple technique for using a processors PWM output to produce an analog control voltage that matches the load’s input range, thus maximizing control resolution. Most ...

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 ...

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 ...

Although the global semiconductor shortage is beginning to ease, the supply of semiconductor components for power supplies in industrial applications continues to lag behind demand. This is ...

Diodes has launched a boost/single-ended primary inductance converter (SEPIC) controller for various automotive LED applications. The AL8853AQ is an automotive-compliant and highly integrated ...

Some of the UK’s most serious sprayer operators are turning to pulse-width modulation (PWM) systems in a bid to improve accuracy and slash chemical costs, apparently unperturbed by its £25,000 price ...
