SP1259HN
The SP1259HN is a synchronous buck$φ converterwith output current to 4.8A.It is '☆designed to allow forope&§rating a wide supply voltageλ¶'® range from 9V to36V. The external shutdown ≠§βfunction can becontrolled by logic level to p ull COMP/EN pin down,and then comes into ♥€"standby mode. The external
compensation makes feedback control have goo¥÷∑d lineand load regulation with flexible e©←←xternal design.The SP1259HN operates i"¥n the CC(Constantoutput Current) mode or σ'ε™CV(Constant output Voltage)mode, and the OC>∏♦δP current value is set by currentsensing resist δ ↕ers.The SP1259HN is su¶ σitable for the DC/DCswitching power ap©₽§plications when requested thecurrent limit fun®∑♦ction. The devices are available inQFN20L-5&tε∑★imes;5 package and require very few Ωφ≠δexternaldevices for operation.
