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 pullγ COMP/EN pin down,and then comes into standby mode. The ext♣ernal

compensation makes feedback control have good lineand load regulation with flexible ex®ternal 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.
