Functional Description

2.2.6

Short Term Bus Under voltage

Short-term PFC bus under voltage (Figure 12) is detected if the duration of the under voltage does not exceed

800 ms (timer remains below t < 800 ms). In this case, the PFC and inverter drivers are immediately switched

off and the controller continuously monitors the status of the bus voltage in a latched power-down mode (ICC <

170 ÂµA). If the signal at the OVP PIN exceeds 18 ÂµA and the rated bus voltage is above 12.5 % while the timer

is below t < 800 ms, the controller restarts from power-up. The timer resets to 0 when entering the run mode.
