Is there a KiCad symbol and footprint for the TC7660SEPA?
Yes. The symbol is 4ms_IC:TC7660S and the footprint Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TC7660SEPA?
PDIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the TC7660SEPA datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the TC7660SEPA?
JLCPCB lists it as part C640849, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TC7660SEPA?
Parts like it in the library: the MC34063ECN by STMicroelectronics, the UC3845AN-TD by TDSEMIC, the DK125 by Shenzhen DongKe Semicon and the MC34063EBN by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
