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 ...

iWatt Inc. introduces the iW1810 ac/dc digital PWM IC, which integrates an 800-V bipolar power transistor as well as numerous features to save external components and ensure high efficiency. The ...

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, ...

Knowing what you know today about the enormous penetration of power supplies and their component parts at every level of electronic products and systems, would you believe that this huge industry rode ...

Tight foundry capacity has constrained semiconductor supply, with PWM ICs in particularly serious shortages. The IC shortages are delaying shipments of end-market devices that are badly needed to ...

The supply of handset-use power management ICs remains severely tight, prompting the chip suppliers to transition to 12-inch wafer manufacturing, according to industry sources. PWM IC suppliers ...

PWM waveforms are commonly used to control the speed of DC motors. The mark/space ratio of the digital wave-form can be defined either by using an adjustable analogue voltage level (in the case of a ...

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") today announced the launch of “TB67B000AHG,” a new three-phase brushless motor driver for home appliances such as ...

Hello,<P>After reading a few post from <B>stickmewithneedles</B> and <B>Unobtanium</B>, I'm planning on making a thermal fan control circuit employing PWM. <P>I've no EE degree, but I love electronics ...
