Description
The HVLED001 is an enhanced peak current
mode controller capable of controlling mainly high
power factor (HPF) flyback or buck-boost
topologies in LED drivers having an output power
up to 150 W. Some other topologies, like buck,
boost and SEPIC can also be implemented.
ST’s innovative high voltage technology allows
direct connection of the HVLED001 to the input
voltage in order to both start up the device and
monitor the input voltage without the need for
external components.
Advanced features are embedded to control
either the output voltage or output current
precisely and reliably using a reduced number of
components, mainly passive. Startup and light-
load conditions are managed by dedicated
operating schemes to improve the quality of
output variable regulation in the final application.
Abnormal conditions such as open circuit, output
short-circuit, input overvoltage/undervoltage, and
circuit failures such as 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.
