SP1259HN
The SP1259HN is a synchronous buck converterwith output current to 4.8A.It is designed t§o allow foroperating a wide supply voltage range from 9V£ to36V. The external shutdown function can becontrolled by logic leve₹l to pull COMP/EN pin down,and then comes into standb₽y mode. The external
compensation makes feedback control have good lineand load regulatio₹n with flexible external design.The SP1259HN operates in the CC(Constantoutput Current) m•ode or CV(Constant output Voltage)mode, and the OCP current value is set by cur↑rentsensing resisters.The SP1259HN is suitable for the DC/DCswitching" power applications when requested thecurrent limit function. πThe devices are available inQFN20L-5×5 package and require very few ext₹ernaldevices for operation.
