LM26480 1.5-A Buck Regulators and Dual 300-mA LDO

LM26480 1.5-A Buck Regulators and Dual 300-mA LDO

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 mini.
