Other Parts Discussed in Thread: TPS23730
Hi
According to section 8.4.7 Advanced Start-Up and Converter Operation.
1.) In this context, it doesn't explain how does advanced startup works, what's the difference between a normal startup and an advanced start up, I know the advanced start-up can reduce the capacitor, can someone tell me why?
2.) Converter switching is disabled while CBULK charges and VRTN falls from V VDD to nearly V VSS; VRTN is ground why said from Vdd to Vss?
3.)In this context, if the discharge was not already completed, then it is gradually recharged until it reaches ~0.25 V (VSSOFS in closed-loop mode), in the discharge interval, why it is recharged?
4.)in this context, If the converter control-bias output rises to support VVCC before it falls to VCUVLO_F (~6.1 V), a successful start-up occurs. what does this sentence means?
