Product details

Description

Package The LC5581AS and LC5581LS are quasi-resonant LED driver ICs.The ICs can also operate in PWM mode.The ICs support isolated and non-isolated buck circuits and buck-boost converters.The ICs provide the systems that can comply with the harmonics standard (IEC61000-3-2 Class C) in all conditions, including a light load condition.These systems, moreover, can be achieved by 1 converter system that requires no input electrolytic capacitor.The ICs employ the average current and quasi-reson
