Last time, I showed you a simple PWM block and an open source UART core. This time, I’ll put these parts together to create a PC PWM output peripheral. With working code (working, at least, in ...
How to use unfiltered PWM to drive high power loads. How to properly set the PWM duty cycle for high power loads. How to drive an incandescent lamp using PWM. Sometimes it’s necessary to drive a ...
The trend is clear: The Power Supply industry is starting to accept full-digital control of Switch Mode Power Supplies (SMPS) as a viable control technology. The advantages this trend brings are ...
Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...
Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...
How to set up an PIC microcontroller to deliver high-precision frequencies from 1 Hz to 4 MHz. Examples of the frequencies delivered by this microcontroller design. In timing applications, a time-base ...
The TC648B is a PWM fan speed controller with auto-shutdown, fan restart, and FanSense™ technology for fault detection. The device features over-temperature indication, efficient PWM drive, and it ...
