SP1259HN
The SP1259HN is a synchronous buck∏§ converterwith output current t•εo 4.8A.It is designed to allo∏£w foroperating a wide supply volt¥¶ age range from 9V to36V. The external s ←hutdown function can becontrolled b§→y logic level to pull COMP/E≈&↑N pin down,and then comes into ≈®standby mode. The external
compensation makes feedback contr"λ↔ol have good lineand loa✘"€λd regulation with flexible ext↕♦ernal design.The SP1259HN o™πεperates in the CC(Constantoutput Curren±≤t) mode or CV(Constant ↔δφoutput Voltage)mode, and the Ω∑∏OCP current value is set by curre™ ∑<ntsensing resisters.The SP1259HN ♥σφ✔is suitable for the DC/DC<<"switching power applications when☆₹ requested thecurrent limit function. T←©∞he devices are availabl∏★e inQFN20L-5×5 package and requi↔< re very few externaldevicesλ'© for operation.
