The SP1259HN is a synchronous buck converterwith output current to 4.8A.It is designed to allow fαoroperating a wide supply voltage range from 9V to36V. The ex‍ternal shutdown function can becontrolled 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 regulation with flexible external €design.The SP1259HN operates in the CC(Constantoutput Current) mode oαr CV(Constant output Voltage)mode, and the OCP curren¥t value is set by currentsensing resisters.The SP1259HN is suitable for th>e DC/DCswitching power applications when requested thecurrent limit function.  The devices are available inQFN20L-5×5 package and require very fe✔w externaldevices for operation.
