SP1259HN
The SP1259HN is a syn☆↕chronous buck convertπ♥αerwith output current t∞€±'o 4.8A.It is designed to al≥→low foroperating a wide supply vo'αltage range from 9V to36V. The exte¶<rnal shutdown function can becontrol¥↔γled by logic level to pull COMP/E♠↓↓N pin down,and then comes into standb₹<↓y mode. The external
compensation makes feedback con >trol have good linea✔¶↔₩nd load regulation wi♥ ↓th flexible external design.The S≠≤←✘P1259HN operates in the CC(Const∑±♠✔antoutput Current) mode or CV(Cons'±₹tant output Voltage)mod♣e, and the OCP current value is set by λ currentsensing resisters.The SP1259HN i∏↔s suitable for the DC/DCswitching power± σ applications when requested thecu§ββrrent limit function. The devices÷←Ω are available inQFN20L-5×5 packa✘™&ge and require very few exte®<↕rnaldevices for operation.
