TPS63000: Low power mode of Buck Boost converter using a Microcontroller

HARI T O1
Expert 1385 points
Part Number: TPS63000

Tool/software:

Hi...

I am using TPS63000 in my design and I need to control PS/SYNC pin using a micro-controller.

The input to the buck boost converter is 3V to 4.3V which is coming from a battery. The output of the converter is 3.3V

The microcontroller is working at 3.3V. This 3.3V is coming from TPS6300

I am using a BJT switch to control the PS/SYNC pin.

When micro-controller output is high the BJT will turn on and PS/SYNC will be connected to GND and TPS63000 will go to low power mode.

My circuit is given below .May I know is it fine or not.
