DDR converter in a 48-VFQFPN — three regulated rails from a single input
The PM6641TR: It is housed in a 48-VFQFPN (7x7 mm) exposed-pad package for surface-mount assembly.
Package and board-fit — 48-VFQFPN with exposed thermal pad
The 0.5 mm pitch QFN demands a solder paste stencil with aperture reduction on the centre pad to avoid voiding. Supplied in Tape & Reel (TR) or Cut Tape (CT) — the reel format is the standard feeder-ready option for pick-and-place lines, while cut tape suits prototype or low-volume builds.
Bench validation should include a thermal sweep across the full range to confirm the output regulation and ripple stay within the DDR memory's VTT and VREF tolerance bands.
