Other Parts Discussed in Thread: TPS61163
Hi Team,
It is a smartphone application, and we face an issue that chip do not switch, the LX pin always bypass the VPH_PWR.
We check the schematic, and probe the EN/VIN/PWM pins, they are all good.
We also have tried adjust the PWM voltage or frequency, but not help. Please kindly give us some suggestions that we can try.
Attached schematic, inductor and diode P/N . Please kindly help if maybe there are any component limitation.
Inductor: MRSC252A10-4R7M
Diode: WSB5539N
Thanks
