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
