The STEF512PUR from STMicroelectronics is a power management IC in the Analog & Data Acquisition category. It is supplied in a 10-WFQFN package with a 10-QFN (2x3) supplier device package, surface-mount mounting.
Package and board-fit considerations
The 10-WFQFN package (2x3 mm body) is a fine-pitch, thermally enhanced QFN. The exposed pad on the underside must be soldered to a thermal land on the PCB to achieve the rated thermal performance. The 0.50 mm pitch requires careful solder-paste stencil design to avoid bridging between adjacent pads.
