The AL6562A is a current mode Power Factor Correction Controller and is designed for operating in Transition Mode. With a superior linear performance multiplier, it ensures the device operates over a wide input voltage range with superior THD (Total Harmonics Distortion). The output voltage is controlled by means of an error amplifier and a precise (1% @ TJ = +25°C) internal voltage reference.

The AL6562A is designed to meet stringent energy-saving standards with low start-up current, and can operate with low current consumption when entering stand-by mode.

OVP circuitry increases system robustness, allowing the device to withstand transient caused at start-up and during load-disconnects.
