TPS2121: operating current compare to TPS2113

Part Number: TPS2121
Other Parts Discussed in Thread: TPS2113,

Hi Sir,

My customer is using TPS2113 on their previous generation platform and seeking our advise if we have a newer solution for them.

I propose TPS2121 to them, but on the spec, TPS2121 have higher operating current compare to TPS2113, 300uA vs 55uA.

May i have your help on:

1. Why TPS212 have a higher operating current? is it because it support higher Vin?

2. If customer concern about the operating current(system sleep mode), what other solution you suggest us to promote?

Many thanks,

Patrick
