Package drawing

• Irregular pads (HotRod / flip-chip / module): program from the datasheet land pattern, not the QFN decoder

Top view, to scale, drawn by the same engine the app uses. Letters match the datasheet. In the app you can flip to the bottom view, which is how most datasheets draw it.

Numbers to program

Body D	4 mm
Body E	6 mm
Height (A)	1.03 mm
Pitch e	0.5 mm
Leads / pins / balls	32
Tape	#TRPBF reel
MSL level	3

Laminate LQFN with 6 separate ground pads underneath in a grid. Build from the datasheet drawing.

Values come from the linked datasheet. Always confirm against the datasheet for the exact part number and suffix you are placing, and check the first board.

What to watch on Power / DC-DC

A HotRod part programmed as a plain QFN with a center pad
Suffix mix-ups: R vs T reels of the same part
Bags left open past floor life
