Elektronische Bauelemente SDCGS5581 1Amp 6V 1.5MHz Synchronous DC/DC Buck Converter RoHS Compliant Product A suffix of “-C” specifies halogen and lead-free DESCRIPTION The SDCGS5581 are high-efficiency, high frequency Synchrono us step-down DC-DC regulator ICs capable of delivering up to 1A output currents. The SDCGS5581 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. The output voltage can be regulated as low as 0.6V. The SDCGS5581 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system.
