產品詳細資訊
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. STs 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.
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
