Buck-Boost convertor based on TI TPS63070. EasyEDA Schematic and PCB Layout Review.

Application Desc.

This circuit is for an IoT device running on 3.3/5 v (.5 A nin). Our aim is to use same PCB but set the FB resistor accordingly (R1 and R2).

Power to this PCB will be supplied from a LiPo 3.7v battery (1 or 2).

Input Voltage - 2.7 to 4.2 (Single Battery) / 5.2 to 8.4 (Dual Battery)

Output Voltage: 3.3 / 5


Confirm PM IC Part No.

Confirm R1/R2 values for both (3.3/5v)

Confirm/Changes that PCB layout is consistent with IC lay out guide lines.

Confirm Inductor/Cap values for both (3.3/5v)

Skills: PCB Layout, Electronics, Electrical Engineering, Microcontroller, Circuit Design
