Many switch used in power management chip has a SYNC pin and external clock synchronization, specific application before listen to of have a saying is: use the SYNC SYNC after multiple chip parallel output, and internal MOS flow is reduced,
So want to consult, any two of the same power supply chip (integrated switch, external inductance), as long as the SYNC input synchronous clock, you can output in parallel?
Here I mean the circuit in parallel multiple SW pins connect together, and then using only a LC filter,
