HVLED001B集成电路（IC）的LED驱动器规格书PDF中文资料

HVLED001B属于集成电路（IC）的LED驱动器。由意法半导体集团制造生产的HVLED001BLED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。

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
