El Segundo, Calif.—International Rectifier introduced the IR3651, a synchronous PWM control IC designed for high-performance synchronous DC/DC buck applications with an input voltage range up to 75-V.

A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators,” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...

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 ...

Fig 1. The buck converter schematic shows the voltage feedback loop and the fast peak CMC loop. The current waveform as seen by the shunt is the dominant signal at the ramp of the PWM comparator. Fig ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

Allegro MicroSystems has created a pair of ICs that transmit isolated control signals and power to silicon carbide mosfet gates. AHV85003 is the transmitter and AHV85043 is the receiver, which need to ...
