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 ...

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 ...

The HV9931 is a fixed-frequency, pulse-width-modulated (PWM), offline LED driver IC with built-in power factor correction (PFC). It is designed to control an LED lamp drive using a proprietary ...

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, ...

Milpitas, Calif. – Intersil's Endura ISL6522B is a single-phase dual-mode synchronous-buck PWM controller/driver IC designed to solve start-up problems associated with pre-biased loads such as found ...

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 ...

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 ...
