The SGM61330 is internally compensated, synchronous Buck converter with a wide 3.8V 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 28μA (TYP) quiescent current and ultra-low 2μA (TYP) shutdown current, it is well suited for battery powered systems to prolong battery life. Internal compensation allows quick and low component count design.
The SGM61330 can operate at fixed frequency with moderate or heavy load condition. In light load condition, it enters in the pulse frequency modulation (PFM) mode to improve high efficiency.
The EN employs an enable divider to establish a precision threshold that simplifies UVLO adjustment, device on/off control and power sequencing. Thermal shutdown and output short-circuit protection (hiccup mode) are also provided.
The SGM61330 is available in a Green TQFN-2×3-12AL and SOIC-8 (Exposed Pad) package.
