Synchronous:How to distinguish between synchronous and asynchronous? A synchronous switching power supply has two MOSFETs, one is the switching transistor, and the other is the synchronous transistor. When the switching transistor is off, the synchronous transistor turns on to continue the current flow. Synchronous switching power supplies have higher efficiency. A switching power supply that … Read more
01 Bridge Researchers at the University of Massachusetts used a 3D printing technology called cold spray on a bridge built in 1949 in western Massachusetts. The cold spray technology works by injecting high-speed metal powder particles, which bond with and cover the damaged areas of the bridge’s metal beams. Repeated spraying can form a multi-layer … Read more
In the field of 5V power chips, a feedback voltage of 0.6V has been an unbreakable “iron rule” for a decade. As semiconductor process technology enters the nanometer level, the SOC supply voltage continues to decrease to balance performance, power consumption, and transistor reliability. For example, in TSMC’s A16 process, the SOC supply voltage will … Read more
