SP1259HN
The SP1259HN is a synchronous buck convσ'£ erterwith output current to 4.8A.It is deΩ™¶signed to allow foroperatinβ₩g a wide supply voltage range from 9V to36₽δV. The external shutdown funλ'λλction can becontrolled by loπδεgic level to pull COMP/EN pi♣¥n down,and then comes into standby mode. Th★₹">e external
compensation makes feedback control have good lin£↓↔®eand load regulation with flexibl•±e external design.The SP1259HN oper✘€Ωφates in the CC(Const'σantoutput Current) mode or CV(Constant output V©σ♣oltage)mode, and the OCP current value is set b↑Ω★¥y currentsensing resisters.The SP1259HN iσ♥αs suitable for the DC/DC•♠switching power applications when re€λ≤quested thecurrent lim♠♠it function. The devices are available inQFN20♦ L-5×5 package and require very few exβ≥ternaldevices for operation.
