Recently, I tuned 28335. The program runs normally through the emulator load and burns into the flash, but there is no signal on the clkout pin. After testing, the epwm output frequency and the freque...
I would like to ask you: What is the cutoff frequency of this low-pass filter? How to calculate it? What kind of structure does it belong to? Thank you....
I am working on a design recently and need a power supply with an input voltage of 2.6-4.2V, a constant output of 9V, and a peak value of 500ma to power the uc3525 driver. Or 12V, 500ma is even better...
Preparation before layout: 1 Check whether the snap point is set correctly. The snap point is 0.1 for 08 process, 0.05 for 06 process, and 0.025 for 05 process. 2 The cell name cannot start with a num...
