Questions

Is there a KiCad symbol and footprint for the TM1620B?

Yes. The symbol is EasyEDA_Cloud:TM1620B and the footprint Package_SO:SOP-20_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TM1620B?

SOP-20, with 20 pins. Its footprint is drawn on this page.

Where is the TM1620B datasheet?

TM publishes it: the Datasheet link on this page opens it.

Where can I order the TM1620B?

JLCPCB lists it as part C2837156, with 2 in stock; the sellers' links on this page open their listings.

What can replace the TM1620B?

Parts like it in the library: the HT16K33A-20SOP by Holtek Semicon, the HTM1620 by HXY MOSFET, the MP3398AGY-Z by Monolithic Power Systems and the MP4653GY-Z by Monolithic Power Systems. Check their datasheets: a part that fits the footprint may still differ in its ratings.
