The TPS65070RSLR is a 5-channel power management IC from Texas Instruments integrating two LDOs alongside step-down converters, purpose-built for OMAP and mobile application processors. Its input supply range of 2.8 V to 6.3 V covers single-cell Li-ion, USB, or regulated 5 V rails — the designer sizes the input capacitor bank for the transient load of the processor core.
Supply rail and package constraints for layout
The 2.8 V to 6.3 V input range sets the bulk capacitance and input filter corner — a 10 µF ceramic plus a 0.1 µF bypass per supply pin is the typical starting point. Surface-mount assembly with the 48-VFQFN package follows standard QFN reflow profiles. The part is ROHS3 compliant, so no lead-free exemption paperwork is needed for EU-market builds.
The base product number TPS65070 covers multiple package variants; the RSLR suffix identifies the 48-VQFN reeled option.
