HVLED001B
Overview
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.
- Quasi resonant (QR) topology
- Primary side regulation of output voltage
- Direct optocoupler connection for current loop regulation with feedback disconnection detection
- 800 V high voltage startup
- High power factor and low THD in universal range
- High efficiency and output stability in wide voltage and current range
- Extremely low standby power at no load condition
- Programmable frequency foldback
- Integrated input voltage detection for high power factor capability and protection triggering
- Latch-free device guarantee by smart autoreload timer (ART)
