HVLED001ATR集成电路（IC）的LED驱动器规格书PDF中文资料

HVLED001ATR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HVLED001ATRLED 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 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 builtin to guarantee automatic application recovery,

without loss of reliability
