HVLED001A
Offline controller for LED lighting with constant voltage primary-
sensing and high power factor
Datasheet
-
production data
Description
The HVLED001A is an enhanced peak current
mode controller capable of controlling high power
factor (HPF) flyback or buck-boost topologies in
LED drivers that have an output power of up to
150 W. Other topologies, such as buck, boost and
SEPIC, can also be implemented.
ST’s innovative high voltage technology allows
direct connection of the HVLED001A device to
the input voltage to start up the device and to
monitor the input voltage, without the need for
external components.
The device embeds advanced features to control
either the output voltage or the output current
precisely and reliably using a reduced number of
mainly passive components. Startup and light
load conditions are managed by dedicated
operating schemes to improve the quality of the
regulation of the output variable in the final
application. Abnormal conditions such as open
circuit, output short-circuit, input overvoltage/
undervoltage and circuit failures like open loop
and overcurrent of the main switch are effectively
controlled.
A smart auto-recover timer (ART) function is built-
in to guarantee automatic application recovery,
without loss of reliability.
