Topology is frequently discussed in the realm of electronics PCB boards. It is a reflection of the overall framework of hardware, including three common topologies in non-isolated power supplies: buck, boost, and buck-boost. In the routing process of PCB boards, there is also a certain topology relationship among each device. Let’s explore this further.
1. Point-to-point topology
This is a simple topology with a single driver and a single receiver.
2. Compact tree topology
Drivers and receivers are strung together with short interconnecting transmission lines. Starting with the main driver, a transmission line is used to connect to a buffer located close to the main driver. This process continues, connecting each unconnected buffer to a nearby buffer until all connections are complete.
3. Daisy chain topology
All buffers are connected using short interconnecting transmission lines. Each buffer is connected to two other buffers using transmission lines. Starting from the main driver, each unconnected buffer is connected to a nearby buffer, forming a chain of connections.
4. Star topology
Beginning with the main drive, connections are made to other drives through cables. All receivers are then connected through cables to the last drive in the chain. If there is only one drive, it is placed in the center of the star.
5. Distal cluster
Similar to a star topology, the last driver connected to the chain of drives is linked to a “T” node via a long transmission line. The receivers are also connected to this “T” node, clustering them together.
6. Hybrid topology
This involves a combination and crossover of the conventional topologies mentioned above on a PCB board.
