IL6562D

IL6562D POWER FACTOR CORRECTOR CIRCUIT functional equivalent L6562 STMicroelectronics DESCRIPTION The power factor correction is specifically de- signed for use as a preconverter in electronic ballast and in autonomous power converter applications. The circuit is purposed for AC-DC adapters, battery chargers and some other applications. The circuit performs voltage-current phase shift compensation by means of creation of phase lead in some nodes of circuit to reduce active parasitic losses in the conductors and distributive equipment. The IC is available in SO-8 plastic (MS-012AA) case Plastic case MS-012AA (SO-8) Fig. 1 – Device view Features: Transition-mode control of PFC Original multiplier design minimizes THD of AC input current Precise adjustable output overvoltage protection Low start-up supply current Low (≤70μa) stand-by supply current Operating supply current not exceed 5mA Extended supply voltage range up to 22V Build-in filter on current sense Disable function Precise internal reference voltage source Two gate output stage r with undervoltage pull-down and voltage regulator SO-8 (MS-012AA.) case The weight of IC not exceeds 0,15 g.
