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 shut✔down 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 des★ign.The SP1259HN operates in the CC(Constantoutput Current) mode or CV(Conεstant output Voltage)mode, and the OCP current value is σset by currentsensing resisters.The SP1259HN is suitable for the DC/DCswitching po>wer applications when requested thecurrent limit function. T he devices are available inQFN20L-5×5 package and require v∞ery few externaldevices for operation.
