SDCGS5581 Datasheet | SeCoS Halbleitertechnologie GmbH

Elektronische Bauelemente 1Amp 6V 1.5MHz Synchronous DC/DC Buck Converter Ro HS pliant 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. This device offers two operation modes, PWM mode and PFM Mode switching control, which allows a high efficiency over the wider range of the load. Features High Efficiency: Up to 96% 1.5MHz Constant Frequency Operation 1000m A Output Current No Schottky Diode Required 2.6V to 6V Input Voltage Range Adjustable Output Voltage Range Options from 0.6V to VIN 100% Duty Cycle Low Dropout Operation Low Quiescent Current: 35µA Slope pensated Current Mode Control for Excellent Line and Load Transient Response Short Circuit Protection Thermal Fault Protection Inrush Current Limit and Soft Start <1µA Shutdown Current Ro HS pliant, 100%Pb & Halogen Free DFN2- 2 REF.
