Dear TI experts,
I want to use TPS62172 to convert 3.7V of lipo battery to 3.3V output.
Can I ask 4 design related questions?
1. Can the 100kΩ pull-up resistor in the picture above be removed if I don't use the PG pin and connect it to ground?
2. The current of my system is about 20mA. Do I need to add extra resistance on the basis of the above picture?
3. Regarding the 2.2uH inductor, can VLS252012ET-2R2M be used in addition to the recommended model on page 14 of the datasheet? Does current matter?
4. If it's always on, can I just short the Vin and EN pins in the layout?
Best regards,
Will
