Design overview

This design is a start-up simulator that produces three different start-up pulses to test automotive systems up to 50W. The microcontroller sets the output voltage of the synchronous buck in the 2-15V range based on the programming curve. The output current range is 3.3-25A. It is a complete system that provides all the information needed to make the device.

CAT6A Flat Patch Cable

CAT6A Flat Patch Cable, A Flat cable design helps improve the look of your home or office. Flat cables are super flexible and can be run under the carpet or bent through corners or into desks.


A double stranded DU line from the latest BAI in ISO/IEC 11801 class 6A /F standard 1. It is mainly used for the application and development of ten thousand ZHI bit Ethernet DAO network technology.CAT6A is an shielded twisted pair , thus providing a combined attenuation to crossposition ratio of 500MHZ, more than twice that of CAT6 and Cat5e patch cable, with a transmission rate of up to 10Gbps. In the CAT6A Ethernet Cable, each pair has a shield layer, and four pairs of wires together have a common shield layer.
In terms of physical structure, the additional shielding layer makes the CAT6A have a larger diameter.Another important difference is its ability to connect hardware. The parameters of the cat7 of systems require that all pairs of wires provide at least 60DB of integrated proximal winding at 600MHZ.The cat5e systems only require 43DB at 100MHZ and 46DB at 250MHZ for the CAT6.
