1.The TPS549D22 defaults to 650kHz switching frequency with the 1xR ramp generator and only allows this to be adjusted via PMBus. 如果是1/2R,需要通过PMBUS吗?还是默认650Khz? 如果原来PCB没有预留PMB_DATA ,PMB_CLK,是不是不能替代? 2.TPS548D22 designs which selected lower switching frequencies…
When it comes to MOS transistors, everyone knows about NMOS and PMOS.
So how can we tell the difference between them?
The biggest distinction lies in their substrate structure.
In circuit diagrams, NMOS has a P-type substrate, while PMOS has an N-type…
