Supply voltage and quiescent current — portable equipment fit
The TPS6591104DA2NMA accepts a wide input range of 1.7V or 2.7V to 5.5V, covering single-cell Li-ion, two-cell alkaline, or USB VBUS rails without a separate pre-regulator. Its 320 µA supply current sets the standby floor for the PMIC itself — in a battery-powered device drawing 10 mA average, the PMIC overhead is about 3.2% of the system budget, leaving room for the processor and peripherals.
Package and layout — 98-NFBGA (9x6 mm)
The 98-NFBGA package measures 9x6 mm with a 0.50 mm ball pitch typical of TI's BGA PMICs. The fine pitch demands a 4-layer or more PCB for fan-out; the inner layers carry the supply and ground planes that keep the PMIC stable. No reel option is listed — if you need tape-and-reel for automated assembly, confirm availability with your distributor at quote time.
TI continues to manufacture and support this PMIC for new designs. No lead-free process change needed on the assembly line.
