HVLED001B

High power factor flyback controller with constant voltage

primary-sensing and ultra-low standby consumption

Datasheet - Production data

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.

SSOP10

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.

Features

 Quasi resonant (QR) topology

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.

 Primary side regulation of output voltage

 Direct optocoupler connection for current loop

regulation with feedback disconnection

detection

 800 V high voltage startup

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.

 High power factor and low THD in universal

range

 High efficiency and output stability in wide

A smart Auto Recover Timer (ART) function is

built in to guarantee an automatic application

recovery, without any loss of reliability.
