Hi friends,
I have a doubt.
In the diagram above, the boost converter is used to power a GSM module that operates in 3.6V.
TPS610995DRVT has a fixed output of 3.6V and VBAT is a primary battery of 3.6V and can be enabled whenever required.
The purpose of the boost converter is that the GSM module will operate only on the range of 3.4V to 3.8V, so when the battery voltage is below 3.4V, the device will become useless.
The controller is driven directly from the battery.
When the boost converter is enabled it may take more current from the battery and may cause the battery voltage to drop below a certain level which ma lead to reset the controller.
So can I connect the output of the boost converter to any one of the VCC pins of the controller as an alternative source of power?
But the problem I am challenging is that all the VCC pin of the controller are connected internally. So when I connect any one VCC pin to the output of boost converter and all other VCC pin to the battery are conclusively connected to the battery itself (simply saying the input and output of the boost converter is connected to the battery)
How can I solve this problem?
