Description
The L6564H is a current-mode PFC controller operating in transition mode (TM) which
embeds the same features existing in the L6564 with the addition of a high voltage startup
source. These functions make the IC especially suitable for applications that must be
compliant with energy saving regulations and where the PFC preregulator works as the
master stage.
The highly linear multiplier, along with a special correction circuit that reduces crossover
distortion of the mains current, allows wide-range-mains operation with an extremely low
THD even over a large load range.
The output voltage is controlled by means of a voltage-mode error amplifier and an accurate
(1% @T
feedforward function (1/V
also considerably improves line transient response in the case of both mains drops and
surges (“bi-directional”).
In addition to overvoltage protection able to control the output voltage during transient
conditions, the IC also provides protection against feedback loop failures or erroneous
settings. Other onboard protection functions allow brownout conditions and boost inductor
saturation to be safely handled.
The totem pole output stage, capable of a 600 mA source and 800 mA sink current, is
suitable for a high power MOSFET or IGBT drive. This, combined with the other features
and the possibility to operate with ST's proprietary fixed-off-time control, makes the device
an excellent solution for SMPS up to 400 W that requires compliance with EN61000-3-2 and
JEITA-MITI standards.
