DESCRIPTION

The BLL2620 is a synchronous rectified step-down converter that provides wide 5V to 28V input voltage range and 5A continuous load current capability.The BLL2620 can operate at PFM mode to achieve high efficiency which can be programmed by a resistor tied between RT to ground and reduce power loss at light load.The COMP pin allows the loop compensation of the switching regulator to be optimized based on the programmed switching frequency,allowing for a fast transient response.

The BLL2620 protection function includes cycleby-cycle current limit,hiccup short circuit protection,UVLO and thermal shutdown.Besides,internal soft-start prevents inrush current at fast power-on.

The BLL2620 requires a minimum number of readily available standard external components and is available in QFN4X4-14 package and provides good thermal conductance
