SY8286B Overview
The SY8286B develops a high efficiency synchronous step-down DC/DC regulator with 3.3V fixed output voltage and 6A current rating. The device integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The SY8286B also integrates a 3.3V/100mA LDO with bypass switch and individual enable control.
