SG Micro SGM61430

The SGM61430 is an internally compensated, synchronous Buck converters with a wide 4.5V to 36V input voltage range and 3A output current capability. The 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) quiescent current and ultra-low 0.6μA (TYP) shutdown current, it is well suited for battery powered systems to prolong battery life. Internal compensation allows quick and low component count design.
