The SGM61430A is an internally compensated, synchronous Buck converter 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, they are well suited for battery powered systems to prolong battery life. Internal compensation allows quick and low component count design.
SGM61430A can operate at fixed frequency with moderate or heavy load condition. In light load condition, the device enters in the pulse frequency modulation (PFM) mode to improve high efficiency.
The EN/SYNC 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 SGM61430A is available in a Green SOIC-8 (Exposed Pad) package and can operate over -40℃ to +125℃ ambient temperature range.
