Hi,

I am new to electronics design and i am confused in selecting the proper regulator,please help.

I designed a schematic using BQ24075 to power device running on battery(3.7 nominal voltage) and first i selected AMS1117 as regulator but it is not working and i realised due to drop out voltage OF AMS1117-3.3 it requires minimum 4.4 to operate.

Can i use TPS63070/TPS63060 to regulate voltage coming from battery to get regulated 3.3V and i require only max. Of 1A current for my application and current rating of both TPS63060/TPS63070 ics is much higer than 1A.

Is it a good solution to use TPS63060/TPS63070 because current ratings are high.

If it is good to use which one should i go for TPS63060/TPS63070?

If both are not good which IC should i select.

My requirements are vout =3.3V ,iout = 1A and iq have to be as low as possible for powering the whole device

Thanks and regards,

P.Akhil.

Dear Sir,

TPS63060 has a little bit lower Iq.

Since the Vo=3.3V, if the battery voltage is always higher than Vo, you can also use a buck converter.

Dear sir,

The battery voltage is not always higher than 3.3V i need to use buck boost.
Can I go with TPS63060 now for input of lower side battery voltage of 3 V to higher threshold voltage from BQ24075 Vout 5.5v to get a output of 3.3V,1A?

Thanks and Regards ,

Akhil.
