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 ...
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 ...
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 ...
This versatile Design Idea survives and reports open- and short-circuits, not to mention multiplying efficiencies.
Wednesday 16 February 2022 Global semiconductor sales hit record high in 2021, says SIA The global semiconductor industry ...
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 ...
IRVINE, Calif.--(BUSINESS WIRE)--Toshiba America Electronic Components, Inc. (“Toshiba”) has launched the “TB67B000AHG,” a new three-phase brushless motor driver for home appliances such as ...
After reading a few post from stickmewithneedles and Unobtanium, I'm planning on making a thermal fan control circuit employing PWM. I've no EE degree, but I love electronics. Details(pdf, page 13) of ...
Pulse width modulated (PWM) amplifier chips generate a current that switches between high and low output levels. The analog signal input controls the duty cycle of an output pulse train that switches ...
