TPS63060: Design of a battery power supply for a LTE-Modem with a LI-SOCL2 battery

Part Number: TPS63060

We want to design a 3,6V Li-SOCL2 battery power supply for an LTE-Modem application. Is it possible to use the TPS63060DSCT for this design? Does someone know a reference design to overcome with the 1A pulses needed from the Modem, witch couldn't directly be delivered by the lithium batteries (only 200mA continuous current and 400mA pulse current). Thanks for your Help.

    Dear Sir,

    What is the Vin range and the Vout range? I want to check whether the TPS63060 is the best choice.

    Vin is 3,6V or 7,2V (depending of the use of 1 or 2 3,6V Li-Socl2 batteries in serie), whatever is better.

    Vout should be near 3,4V (for the modem and the uC).

    The device is battery powered, and must have a long stand alone time. So the stand-by current of the power converter (with only the uC working) must be very low (ideally only some uA).

    Our problem is that the batteries couldn't overcome with the 1A pulses needed by the modem. So we need to use some capacitors or coils to maintain a stable output voltage, even in the case of a 1A short pulse. It is such a design guide that we search for this application.

    Thanks a lot for your answer.

    It seems you post two threads of the same topic.

    Please post the thread on the buck converter forum, because what you need is a buck converter.
