8. Limiting values
Table 3.
In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured with respect to power
ground (pin 2); positive currents flow into the chip. The voltage ratings are valid provided other ratings are not violated; current
ratings are valid provided the maximum power rating is not violated.

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 to 10 V (typical). This high output voltage will drive all MOSFET brands to the
minimum on-state resistance.
During start-up conditions (V
voltage is actively pulled low.
The TEA1762T has two ground connections. The sense ground ensures an increased
accuracy of the output voltage of the switched mode power supply and can also be used
to compensate for cable losses on the output of the converter. The grounds are internally
connected via two anti-parallel diodes.
