HVLED001 LED照明驱动器

HVLED001

Offline controller for LED lighting with constant voltage primarysensing  and high power factor

LED照明驱动器 Power Conversion

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.

Features HVLED001

 Quasi resonant (QR) topology

 Optimized output voltage accuracy at any load

(PSR mode)

 Improved transient response and startup time

 Direct optocoupler connection for current loop

regulation with feedback disconnection

detection

 800 V high voltage startup

 High power factor and low THD over wide

range of input voltage and load variations

 High efficiency and output stability over wide

voltage and current range

 Low startup and quiescent current

 Programmable minimum off-time

 Integrated input voltage detection for high

power factor capability and protection

triggering

 Latch-free device guaranteed by smart autoreload

timer (ART)

 0-10 and PWM dimming compatible

 Remote control pin

Applications HVLED001

 Single stage LED drivers with high power factor up to 75 W

 Two stages LED drivers up to 150 W
