Other Parts Discussed in Thread: TPS62808, TPS62912, TPS62913, LM26420
Hi,
We are exploring a 5V -> 3.3V/1.2V DC-DC converter for our upcoming design. The requirements are
1. This should receive 5V from USB-C as its input
2. It should be able to provide 600mA for 3.3V output rail and around 2 - 2.5A for the 1.2V output rail
3. It should guarantee a 100us settling time for the 3.3V output supply to mitigate reliability risks
I looked at TPS62420 as it was used on prior designs but its main limitation is that it does not meet peak current requirements for scenario #2 for the 1.2V output. Also we are not sure about #3 for this part.
Please suggest a suitable part number that meets all requirements 1-3.
Thanks,
