Three buck regulators in a 5x5 HVQFN
The MC32PF1550A0EP is a power management IC from NXP integrating three buck regulators in a single 40-HVQFN package measuring 5x5 mm with an exposed thermal pad. The industrial temp grade means the regulator loop stability and output accuracy are guaranteed across the full range, not just at 25°C.
The 40-VFQFN exposed-pad package (supplier device package 40-HVQFN, 5x5 mm) requires a thermal land pattern on the PCB to pull heat from the die through the paddle. The Tray packaging is typical for volume assembly; the tray orientation suits pick-and-place without a reel changeover. Surface-mount assembly with the HVQFN package means the PCB layout must account for the 0.5 mm pitch perimeter pads. The exposed pad's solder paste coverage should be about 50-70% of the pad area to avoid voiding and to control the standoff height.
