Texas Instruments  LM26480QSQ-AA/NOPB

The LM26480-Q1 is anautomotive-qualified multi-functional power management unit (PMU), optimized for low-powerdigital applications. This device integrates two highly efficient 1.5-A step-down DC-DC convertersand two 300-mA linear regulators. The DC-DC buck converters provide typical efficiencies of 96%,allowing for minimal power consumption. Features include soft start, undervoltage lockout, currentoverload protection, thermal overload protection, and an internal power-on-reset (POR) circuit,which monitors the output voltage levels on bucks 1 and 2.
