DESCRIPTION
Package The ICs can also operate in PWM mode. 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-resonant controls: the average current control realizes high power factors, whereas the quasi-resonant control contributes to high efficiency and low noise. Having a rich set of protection features, the ICs can provide more costeffective power supply systems with fewer external components.FEATURES
