Other Parts Discussed in Thread: TPS61024

Hi,

I'm using this TPS61020.

My requirement is 

Vin=6V (4 x alkaline battery)

Vout=3V @ 1000mA

but this is boost converter IC.

it can work as buck boost in this specific ic?

how to connect the circuit?

any one can explain the circuit?

    Hi 

    TPS61020 is a boost device and can't not support Vin 6V, Vout=3V at 1A. Will the battery voltage drop below 3V, if so you need a buck boost converter. If not, please choose a simple buck.

    Hi

    This TPS61020 is the VIn = Vout is that correct?

    ex. Vin = 3V, Vout = 3V

    is that Vout is below then the Vin is that correct or any other specification in that TPS61020.

    what is the TPS61024 Vout is 3V but what is the Vin Voltage? when i give the 6V input is that working the with Vout 3V constant? 

    Please kindly refer the one IC for my requirement?

    my requirement is Vin = 6.5V, Vout = 3V or adj IC. @ max 1.5A current.

    Hi

    TPS61020 can't support  VIN=6V and VOUT=3V, the thermal won't pass. Because this is under down mode, Vin-Vout is not allowded to be larger than 0.5*Vin.
