SP1259HN
The SP1259HN is a synchronous buck ±±©λconverterwith output α&βcurrent to 4.8A.It is designed t≠α≥∞o allow foroperating a wide supply ∑÷γvoltage range from 9V to36V. The ★✘∑ external shutdown function can becontr♦♠↔olled by logic level to pull COMε←↔₽P/EN pin down,and then comes intδσπo standby mode. The ®☆£πexternal
compensation makes feedback co≤≤>ntrol have good lineand load re ✘gulation with flexible externa>&εl design.The SP1259HN operates in the Cα☆C(Constantoutput Current) mode or CV(C₹β<αonstant output Voltage)mode, and the Oφ£λ♥CP current value is set×÷ by currentsensing resist®γers.The SP1259HN is suitable f× or the DC/DCswitching power applic£λations when requested thecurrent lim✘σit function. The devices✘€§ are available inQFN20L-5×5 packaσ§±ge and require very few externalde₩☆$ vices for operation.
