The undervoltage lockout function monitors the external supply voltage V
the main line, the internal startup cell is biased and starts to charge the external capacitor C
to the VCC pin. The VCC charge current that is provided by the startup cell from the drain pin is 1.05 mA. If V
exceeds the on-threshold V
undervoltage lockout; therefore no power losses are present due to the connection of the startup cell to the drain
voltage. An hysteresis loop is implemented to avoid uncontrolled ringing at switch-on. Switch-off of the controller
can only take place after the active mode has been entered and V
The maximum current consumption before the controller is activated is about 300 µA.
If V
discharging of the soft-start capacitor C
that the voltage ramp at the SoftS pin starts at zero.
The bias circuit is switched off if Auto Restart mode is entered. The current consumption is then reduced to 300 µA.
Once the malfunction condition is resolved, this block will then turn back on. The recovery from Auto Restart mode
does not require disconnection of the LED drive from the AC line.
