AP2960  is  a  wide  input  voltage,  high  efficiency Synchronous  CC/CV  step-down  DC/DC  converter that operates in either CV (Constant Output Voltage)mode or CC (Constant  Output  Current) mode.AP2960 provides up to 3.0A  output  current  at 350kHz switching frequency.AP2960  eliminates  the  expensive,  high  accuracy current sense  resistor, making  it ideal  for battery charging  applications and  adaptors  with accurate current limit. The AP2960 achieves higher efficiency than traditional constant current switching regulators by eliminating  its associated power loss on the additional current sensing resistor.Protection  features include  cycle-by-cycle  current limit, thermal shutdown, and short circuit recovery.AP2960  are available  in  a SOP8-EP  package  and require very few external devices for operation.
