Tool/software:
Hi,
I'm using the TPS63020-Q1 as a 3.3V buck boost converter for a lithium-ion battery with an input range of 2.6V to 4.1V. This powers a BLE module which, depending on the transmission level spikes between 30-100mA, but has an average current around 100-450uA, when I externally supply the 3.3V. However, when I apply 3.3V through the regulator, it takes around 6-7mA of current, which is way too high for my application. The output voltage is at least correct. Is there any way to improve the efficiency here? I am using a 2.2uH inductor, which is what the data sheet suggests for lower current draws. Do I have any options?
