Six-channel PMIC tuned for OMAP processor rails
The TPS65050RSMT is a 6-channel power management IC from Texas Instruments that integrates four LDOs alongside the main regulators, specifically listed for Mobile/OMAP applications. Its 1.5 V to 6 V input range covers a single-cell Li-Ion battery through USB 5 V, so the PMIC can power the processor directly from the battery or a USB source without an extra pre-regulator. Supply current is 1.25 mA, a figure that matters for battery-life budgeting in handheld OMAP designs — every 100 µA saved extends standby time by hours in a typical smartphone or portable navigation device.
Supply range and quiescent current for portable budgets
The PMIC operates over a 1.5 V to 6 V supply range and draws 1.25 mA supply current. For a design engineer sizing the battery, the 1.25 mA is the overhead the PMIC consumes before any load current — it sets the floor for system idle current.
