SP1259HN
The SP1259HN is a synchronous buck converterwith output current to 4.8A.It is designed to allow foroperating 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 or CV(Constant output Voltage)mode, and the OCP current value is set by currentsensing resisters.The SP1259HN is suitable for the DC/DCswitching power applications when requested thecurrent limit function. The devices are available inQFN20L-5×5 package and require very few externaldevices for operation.
