AL6562A
Description
Features
Transition Mode PFC LED Controller
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.
