Description

The HVLED001B is an enhanced peak current

mode controller able to control mainly high power

factor (HPF) flyback or buck-boost. Some other

topologies such as buck, boost and SEPIC, can

also be implemented.

Primary side regulation and optocoupler control

can be applied independently on the chip, both

exploiting precise regulation and very low standby

power during no load conditions.

The innovative ST high voltage technology allows

direct connection of the HVLED001B to the input

voltage in order to both start up the device and to

monitor the input voltage, without the need for

external components.

Abnormal conditions like open circuit, output

short-circuit, input over-voltage or under-voltage

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 an automatic application

recovery, without any loss of reliability.

Applications

? Single-stage LED drivers with high power

factor

? Two-stage LED drivers
