SGM61430XPS8G/TR

SGM61430XPS8G/TR is a internally compensated, synchronous buck converter with a wide 4.5V to 36V input voltage range and 3A output current capability. This device can be easily used in various industrial applications powered from unregulated sources. Easy compensation and cycle-by-cycle current limit are obtained by peak current mode control. With 64µA (TYP, SGM61430) quiescent current and ultra-low 0.6µA (TYP) shutdown current, this is well suited for battery powered systems to prolong battery life. Internal compensation allows quick and low component count design. It can operate at fixed frequency with moderate or heavy load condition. Application includes industrial power supplies, telecom and datacom systems, general purpose wide VIN regulation.
