      General Description 
               SP1221F  is a  synchronous buck  controller.  It is designed to allow for operating a wide supply voltage range from 9V to 40V. It can drive dual output current to 8A  (4A+4A). The external shutdown function can be controlled by logic level to pull COMP/EN pin down, and then comes into standby mode.  The external compensation makes feedback control have good line and load regulation with flexible external design. 
               SP1221F operates in the Constant output Current mode or Constant output Voltage mode, and the OCP current value is set by current sensing resisters. 
               SP1221F offers comprehensive protection with output over current, output short circuit, output over voltage, over temperature. 
               SP1221F  is offered in MSOP-10L packages and require very few external devices for operation.
