That range means the same PMIC can power a handheld device from battery or USB VBUS without a separate pre-regulator. Inside the 32-VQFN package are two step-down (buck) converters and one LDO. The LDO post-regulates one of the switcher outputs or a separate input, cleaning up ripple for analog or RF loads — a common requirement in handheld/mobile devices. The exposed pad on the 32-VFQFN helps pull heat away from the switching FETs when the ambient climbs.","metaTitle":"TPS65055RSMT PMIC – Dual Step-Down Converter with LDO","metaDescription":"Texas Instruments TPS65055RSMT Power Management IC: dual step-down converter plus LDO, 2.5V–6V input, -40°C to 85°C, 32-VQFN.
