Is there a KiCad symbol and footprint for the PM6644?
Yes. the footprint EasyEDA_Cloud:DFN-10_L3.0-W3.0-P0.50-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PM6644?
DFN-10-EP(3x3), with 10 pins. Its footprint is drawn on this page.
Where is the PM6644 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the PM6644?
JLCPCB lists it as part C1852792, with 220 in stock; the sellers' links on this page open their listings.
What can replace the PM6644?
Parts like it in the library: the LT3973EDD#TRPBF by Analog Devices, the LTC3548EDD#TRPBF by Analog Devices, the LTC3440EDD#PBF by Analog Devices and the LT1913IDD#TRPBF by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
