TPS5420: pin compatible alternative recommendation

Part Number: TPS5420
Other Parts Discussed in Thread: TLV62568, TPS62821, TPS62802

We are looking for a part similar to Ti’s TPS5420 (especially in footprint and pinout) that would generate 3.3V (either by itself or with some adjusting parts) but from a 5V input. The TPS5420 seems to require a 5.5V input and our alternate “USB” source does not bring 5.5V in.
