converter is also activated (providing the soft start capacitor on the FBSENSE pin is
charged). The flyback converter output voltage is then regulated to its nominal value. The
If during start-up the LATCH pin does not reach the V en(LATCH) level before V CC reaches
V th(UVLO) , the LATCH pin output is deactivated and the charge current is switched on
again.
When the flyback converter is started, the voltage on pin FBCTRL is monitored. If the
flyback converter output voltage does not reach its intended regulation level in a
predefined time, the voltage on pin FBCTRL reaches the V to(FBCTRL) level and an error is
assumed. The TEA1752T then initiates a safe restart, while in the TEA1752LT the
protection is latched.
When one of the protection functions is activated, both converters stop switching and the
V CC voltage drops to V th(UVLO) . A latched protection recharges the capacitor C VCC via the
HV pin, but does not restart the converters. For a safe restart protection, the capacitor is
In the event of an overvoltage protection of the PFC circuit where
V VOSENSE > V ovp(VOSENSE) , the PFC controller stops switching until the VOSENSE pin
voltage drops back below V ovp(VOSENSE) . If a mains undervoltage is detected where
V VINSENSE < V stop(VINSENSE) , the PFC controller stops switching until
V VINSENSE > V start(VINSENSE) .
When the voltage on pin V CC drops below the undervoltage lockout level, both controllers
stop switching and reenter the safe restart mode. In this mode the driver outputs are
disabled and the V CC pin voltage is recharged via the HV pin.
