AL6562
Description
Features
Transition Mode PFC LED Controller
The AL6562 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 AL6562 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.
