The SP1259HN is a synchronous buck converterwith outp↔ut current to 4.8A.It is designed to allow foroperating a wide su↕pply voltage range from 9V to36V. The external shutdown function can becoγntrolled by logic level to pull COMP/EN pin down,and then comes into ™standby mode. The external

compensation makes feedback control have good lineand load regulati§on with flexible external design.The SP1259HN operates in the CC(Constantoutput© Current) mode or CV(Constant output Voltage)mode, and the OCP current va&lue is set by currentsensing resisters.The SP1259HN is suitable for the DC/DCswitchin↓g power applications when requested thecurrent limit function. The devices are avaλilable inQFN20L-5×5 package and require very few exter♥naldevices for operation.
