Questions
Is there a KiCad symbol and footprint for the LM3553SD?
Yes. The symbol is Celestial_Driver_LED:TI LM3553SD, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM3553SD?
WSON-12(3x3), with 13 pins.
Where is the LM3553SD datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM3553SD?
JLCPCB lists it as part C3171659, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM3553SD?
Parts like it in the library: the TPS922054DRR by Texas Instruments, the TPS922053DRR by Texas Instruments, the MAX20052ATC+T by Maxim Integrated (Analog Devices) and the RT8463GQW by Richtek Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
