Processor PMIC — NRND, not for new designs
The TPS6590376ZWSR is a Texas Instruments power-management IC (PMIC) for processor-core and system-rail sequencing. It accepts a 3.135V to 5.25V input and is packaged in a 169-ball NFBGA (12x12 mm).
The input supply spans 3.135V to 5.25V, covering standard 3.3V and 5V rails without a separate pre-regulator.
169-ball NFBGA — layout constraints
The 169-NFBGA (12x12 mm) package requires a 4-layer PCB minimum for fan-out. The 0.50 mm ball pitch means via-in-pad or microvias are needed to route the inner balls to the inner layers.
Lifecycle reality — NRND
TI has marked the TPS6590376ZWSR as NRND.
