Part Number: TPS61099

Hello,

1) my project application, NB_IOT gas meter

2) the power rail: DC6V output from dry battery, the through LDO output 5V , throurh DCDC output 3.6V power for NB module.

3) another power rail: DC3.6V from LI-battery, through DCDC output 3.6V power for NB module. The battery voltage will drop, so it needs to be boosted.

please help me to check the TPS61099 can meet the request?

they need meet the boost and buck at the same PCB.

thanks.

    no sure about the block diagram. do you need to buck converter and a boost converter, which means an OR circuit in the output, or a buck-boost converter that means an OR circuit in the input? if the first one, you can use TPS610995 for the boost circuit.
