The TMS320F28335 contains a 12-bit AD converter with the following features: 12-bit ADC core with built-in (sample and hold) S/H Analog input: 0.0V to 3.0V (voltages above 3.0V produce full-scale conv
Abstract: This paper introduces the development process and main development direction of switching power supplies, focusing on the working principle and process of phase-shifted soft-switching conver
In the design of PCB multi-layer boards, four-layer boards are generally used more. So, do you know what are the design rules of PCB four-layer boards?1. Design of four-layer board:(1) Uniform spacing
