Brown Out Ride Through
Brown Out conditions occurs when there is a transient break in input current. During this period the external output bulk
capacitor holds up the voltage to the load until input current is restored. When the input voltage is restored the PFC module
will continue delivering power to the load
After a Brown Out condition where the output voltage has not dropped below 250Vdc, the module will recover when input
power is restored. The PFW signal can be used to monitor input power loss.
