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, ...

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 ...

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 ...

Demand is growing, particularly in emerging economies, for high-efficiency three-phase brushless fan motors that can reduce energy consumption and manage fluctuations in power voltage. Such motors ...

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 ...

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 or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

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