BM2490

BM SEMI BM2490 2.5A CC or CV BUCK ᬜ⥛ 2.5A ᘦ⌕ᘦय़य़ᤶ఼ DESCRIPTION The BM2490 is a monolithic step-down switch mode con verter wi th a prog rammable output current limit. It achieves 2.5A continuous output curren t o ve r a wid e in put suppl y ran ge wi th e xcellent load and line regulation. Th e ma ximum ou tp ut curren t ca n b e programmed b y sensing curren t thro ugh an accura te sense resistor. It can output constant current and voltage. Internal thermal shutdown, cycle-by-cycle current limit protection. The BM2490 requires a minimum number of readily available standard external components. The BM2490 is available in 8-pin SOIC8-EP packages.
