Datasheet - HVLED101TR

COO (Country of Origin):: CN

Advanced high power factor flyback controller with valley locking and maximum power control

The HVLED101 is an enhanced peak current mode controller able to control mainly high power factor (HPF) flyback or buck-boost topologies having an output power up to 180 W. Some other topologies, like buck, boost and SEPIC could also be implemented. Primary Side Regulation of output voltage 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 to directly connect the HVLED101 to the input voltage in order to both start up the device and monitor the input voltage without the need of external components. Integrated valley locking feature guarantees noise free operation during medium and low load operation and maximum power control allows limiting the input power to a level programmable by the user to increase converter safety. Abnormal conditions like open circuit, output short-circuit, input overvoltage or undervoltage, external protection circuitries and circuit failures like open loop and overcurrent of the main switch are effectively controlled. A smart Auto Restart Timer (ART) function is built in to guarantee an automatic application recover, without any loss of reliability.
