TPS61322: TPS613221ADBVR pin to pin device replacement

Hi Jonathan,

Could you please specify what is customer's input, output voltage and output current? There are 12 devices meeting your requirements, but you need specific more about specs so that i can give your the most proper one.

Hi Wenhao,

i was the originator of the request. I found all this devices as well, but problem is, you need to open each product page to check if the part is available (on stock). So i thought, a request to customer support would provide a quicker answer, which isn't obviously the case.

The product is a TV remote with high power IR LED (100mA). So with MCU and all that stuff i qould assume <200mA. It's powered by two AAA cells so input voltage i would say 2..3V, output is 3.3V (fixed).

this is the current schematic with TPS613221ADBV, to bring the prototypes alive it would be neat if there would be a solution which uses same inductances/capacitances.. but i doubt

Thanks in advance

David

Hi David,

Thanks for sharing the operating condition. I found various devices which meet your requirement. But I need to check internally if there is any stock available. What is the required volume per year?

As said... this is for prototype boards.. so 2-5 parts.

When the project is going into production i would assume 1k-2k per anno
