Rc > 100Rs allows control of current of Iout with only milliamps of Ic. Figure 3 shows the idea fleshed out into a complete PWM-controlled 18 V, 1 A grounded-load negative current source. Figure 3 An ...

PWM output and ADC sampling on input have two things in common, there is a low-frequency signal that you’re interested in but it’s mixed together with some high-frequency content that you don ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks ...

This KTB2140 current-mode PWM controller can operate as an active-clamp flyback or forward converter, with a wide 8V to 80V input range. It is optimized for highest efficiency with best-in-class ...

Setting the PWM output to operate at 6.86 MHz ... but for direct hookup to an antenna input, it works just fine. We love to see creative video projects on microcontrollers, so if you’ve figured ...
