Part Number: TPS551892-Q1 Other Parts Discussed in Thread: TPS63010 Tool/software: Hi all, TPS551892 can work with a Vin from 2V75 to 4V2 (battery) and a Vout 3V3 or does it need an external 5V power supply? Thanks
Part Number: TPS551892-Q1 Tool/software: Is the inductance 8.2uH appropriate in the figure? According to the data manual, 4.7uH is appropriate in boost mode but 4.7uH is small in buck mode, so I chose 8.2uH.
The design parameters are
input voltage…
