HI all....
I need some help regarding STEP-UP Booster IC.
i am working on a application where i have to interface SST89E516RD2 and GSM module with Voltage Source from Li-Io batteries voltage range 3v to 4.2V. The battery has a maximum output current of 2.2Amp.
My problem is My controller works on 5V for which i am using step up ic TPS61032-5V to power my controller.
but my GSM module SIM-800 works on 4v. for which i again have to install a second step up IC TPS61030-Adj to power my GSM module. Infact i can connect my GSM module directly with the battery, but i need the system to work till the battery voltage reaches 3.0, in which my GSM module wont work. so i have to add an step up IC to power my GSM module seperately, so that the even GSM Module works with the battery voltage of 3v.
current consumption of my controller is hardly 200 m-amps, but the GSM module consumes around 1.8Amps of current when sending and receiving message.
So can anybody please guide me, if i can use two seperate IC's to power two different components as per their voltage requirement or can you suggest me any single IC where i can power both with their respective voltage, or using two different IC's would be a better choice in this case.
Thanks.
