AL6562

Transition Mode PFC LED Controller

Description

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

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.
