STMicro's HVLED001B is an enhanced peak current mode controller able to control mainly high power factor (HPF) flyback or buck-boost topologies in LED drivers having an output power up to 150 W. Primary side regulation and optocoupler control can be applied independently on the chip both exploiting precise regulation and very low standby power during no load conditions.
The innovative ST high voltage technology allows users to directly connect the HVLED001B to the input voltage in order to both start-up the device and monitor the input voltage without the need of external component.
