TEA1612T
Zero voltage switching resonant converter controller
7.12 Overcurrent protection and timer
The OCP input continuously compares the voltage on pin OCP with Vref(OCP). When the
OCP pin voltage is higher than Vref(OCP), the timer capacitor CT will be charged with Ich
during the next full CF cycle or else the timer capacitor will be discharged with Ileak.
In case the CT voltage exceeds Vtrip(H)(CT) the TEA1612T will switch to shut-down mode.
The timer capacitor will be discharged with Idch until the CT voltage reaches Vtrip(L)(CT)
after which a soft start cycle is started.
7.13 Overtemperature protection
The TEA1612T continuously monitors its temperature. When the temperature exceeds the
Totp(act) level, the TEA1612T will switch to the shut-down mode.
7.14 Brownout protection
The brownout protection compares the actual BO pin with the Vtrip(bo) voltage. If the BO
activates an internal current source Ibo(hys) to create a brownout hysteresis. When the BO
pin voltage becomes larger than Vtrip(bo), the TEA1612T will start-up again.
7.15 PFC disable function
The PFC output pin is an open-drain output. Operation of the PFC pin is internally enabled
when the voltage on the BO pin is higher than Vtrip(bo). When the voltage is lower than
Vtrip(bo), the PFC output is always in the open-drain state.
The PFC output is pulled low when:
The overtemperature protection is active.
The OCP timer has timed out.
The TEA1612T has been set to shut-down.
During the off-time in burst mode.
This PFC output signal can be used to switch off the power corrector in the application
during Burst mode (and during protection) to further reduce standby power losses.
