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.
