The LM26480 is a multi-functional power management unit (PMU), optimized for low-power
digital applications. This device integrates two highly efficient 1.5-A step-down DC-DC converters
and 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, current
overload protection, thermal overload protection, and an internal power-on-reset (POR) circuit,
which monitors the output voltage levels on bucks 1 and 2.
