PMIC companion for Cortex-A8/A9 SoCs and FPGAs
The Texas Instruments TPS65218B101PHPT is a power-management IC (PMIC) designed as a companion supply for ARM Cortex-A8/A9 SoCs and FPGAs. It integrates seven output rails from a single 2.2V to 5.5V input, covering the core, I/O, memory, and auxiliary voltages these processors need.
Seven-rail output and thermal envelope
With seven independent outputs, the TPS65218B101PHPT sequences and regulates the multiple supply domains typical of a Cortex-A8 or A9 system — core, DDR, PLL, and I/O — from a single input source.
This means TI is not actively promoting this variant for new projects, and the part is on a path toward end-of-life. Existing production lines should plan for a last-time-buy or a validated drop-in replacement.
48-PowerTQFP package and footprint
The 0.5 mm pitch demands careful fan-out on a 4-layer board for the seven output rails and their associated passives.
