Functional Description
2.7.1 Short Term PFC Bus Under Voltage
A short term PFC bus under voltage (Figure 28) is detected if the duration of the under voltage does
not exceed 800 ms (timer stays below t < 800ms see Figure 28). In that case, the PFC and inverter
drivers are immediately switched off and the controller is continuously monitoring the status of the bus
voltage in a latched power down mode (I
< 170 µA). If the signal at the LVS PIN exceeds 18µA and
CC
the rated bus voltage is above 12.5% within the timer is below t < 800 ms, the controller restarts from
power up without preheating. The timer resets to 0 when entering the Run Mode.
