... NXP Semiconductors 7.1 Start-up and undervoltage lock-out The IC leaves the under-voltage lock-out state and activates the synchronous rectifier circuitry and also the voltage/current sense circuitry as soon as the voltage on the V is above 8.6 V (typical). As soon as the voltage drops below 8.1 V (typical), the under-voltage lock-out state is re-entered and the SR driver output is actively kept low and also the opto driver outputs are disabled ...

... NXP Semiconductors 7.3 SMPS output voltage and current regulation The output voltage of the flyback Switched Mode Power Supply (SMPS) can be controlled by sensing the output voltage via the VSENSE pin. The feedback loop via the primary controller can regulate the output voltage of the switched mode power supply by regulating the voltage on the VSENSE pin to 2.5 V above the voltage on pin SENSEGND. Also the output current of the fl ...

... NXP Semiconductors 7.9 Driver The driver circuit to the gate of the external power MOSFET has a source capability of typically 250 mA and a sink capability of typically 2.7 A. This permits fast turn-on and turn-off of the power MOSFET for efficient operation. The output voltage of the driver is limited (typical). This high output voltage will drive all MOSFET brands to the minimum on-state resistance ...

... NXP Semiconductors 11. Application information A switched mode power supply with the TEA1762T consists of a primary side discontinuous conduction mode flyback controller, a transformer, and an output stage with a feedback circuit. In the output stage a MOSFET (Qsec) is used for low conduction losses. The MOSFET is controlled by the TEA1762T. The output voltage and/or current is also controlled by the TEA1762T via the opto coupler connection to the primary side ...
