The settings for TPS61220 are as follows.
Vin 2.8~5.0V
Vout 6V
Iout 50mA
Cout:12uF
Loadtype:LED
Vsys is connected to the USB host, lithium-ion battery, and charger, and after setting EN to LOW, I think it is necessary to prevent reverse current of Vin from Vout.
In that case, please tell me whether I should install the diode on the Vout side or on the Vin side (before Cin).
