SP1259HN
The SP1259HN is a synchronous buck ε®&converterwith output curre←Ω÷nt to 4.8A.It is designed to al >♣low foroperating a wide★δα supply voltage range from 9V to36V. Th♣δ★e external shutdown function can♠" becontrolled by logic level to pull C✘ φOMP/EN pin down,and then comes>≥≤© into standby mode. The ex₩→βπternal
compensation makes feedback cσ'α ontrol have good lineand load regulπ¥ation with flexible e$↓πxternal design.The SP1259HN opΩ♥γ®erates in the CC(Constantoutput Cur÷£rent) mode or CV(Constan↔δ∑t output Voltage)mode,σ§ and the OCP current value is®σ set by currentsensing ≈γresisters.The SP1259HN is suitable♠✔ for the DC/DCswitching powe¶βεr applications when requested thecεβurrent limit function. The devicα÷∏es are available inQFN ★20L-5×5 package and require ve ∞ry few externaldevices for o↔♠ ₹peration.
