GS5581B Description
The GS5581/B are high-efficiency, high frequency synchronous step-down DC-DC regulator ICs capable of delivering up to 1A output currents. The GS5581/B can operate over a wide input voltage range from 2.6V to 6V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery.
