AP2962B is a wide input voltage, high efficiency  CC/CV step-down  DC/DC  converter  that  operates  in  either  CV (Constant Output Voltage) mode or CC (Constant Output Current)   mode.  AP2962B   provides  up   to   2A  output current at 230kHz switching frequency. AP2962B eliminates the expensive, high accuracy current

sense   resistor,   making   it  ideal   for   battery   charging applications and adaptors with accurate current limit. The AP2962B   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 frequency foldback at short circuit. AP2962B  are  available  in  a  SOP8  package  and  require very few external devices for operation.
