Other Parts Discussed in Thread: TPS63060
When the input voltage was applied to the Vin terminal as shown below, the Vout voltage was not output by method (1).
(1) Apply 6V voltage of 4 alkaline AA batteries to Vin by switching (OFF → ON)
(2) Apply 6V voltage directly to Vin with a regulated DC power supply
The circuit is created as follows with reference to the recommended circuit in the data sheet.
The inductor used is made by Murata [FDSD0630-H-1 ROM = P3].
When I measured the voltage waveforms of (1) and (2), it became as shown in the image below.
(1) Blue: Vin, Red: Vout, Green: PG
(2) Blue: Vin, Red: Vout, Green: PG
Does the difference in operation affect the rise time to Vin?
Please tell me the probable cause and countermeasures.
