Other Parts Discussed in Thread: LM5168,
- About Internal LDO:
It seems that Vin is 6V and Vout 5V routed to the different internal blocks.
Do we have some information about the overall efficiency when using the on-chip LDO?
Does it make sense not to use the on-chip LDO to power the LDOIN pin? Is it at all supported not to use the on-chip LDO?
Do you have some recommendation (schematics, DCDC IC recommendation, PCB design) to use an external DCDC instead?
Are there some precaution to take with the on-chip LDO if not used to power LDOIN?
What would be the system level careabout in case a DCDC will be used?
Are there some specific design aspects (like power up sequencing, ripple, ..etc) that need to be carefully considered?
For example I have read in the datasheet that 8V is required on Vin for the OTP.
Thanks in advance,
