Product Description

LM61460AASQRJRRQ1 is a 6 A synchronous buck converter with a 3 to 36 V operating input range and an adjustable output starting at 1 V. The AAS option combines automatic light-load operation with spread-spectrum switching. Together with adjustable switch-node rise time and a HotRod layout, these features address conducted and radiated noise at the regulator stage.

Its 6-A synchronous output is adjustable and can be externally clocked. Auto-mode reduces switching activity at light load, which matters when the same rail must support both active operation and a low standby demand.
