Objective data sheet Rev. 1 — 10 August 2012 6 of 13 NXP Semiconductors TEA1792ATS GreenChip synchronous rectifier controller The output voltage of the driver is limited to 10 V (typical). This high output voltage drives all MOSFET brands to the minimum on-state resistance. During start-up conditions (VCC <Vstartup) and undervoltage lockout the driver output voltage is actively pulled low. 8. Limiting values [1] Equivalent to discharging a 100 pF capacitor through a 1.5 k series resistor. 9. Thermal characteristics Table 3. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured with respect to ground (pin 2); positive currents flow into the chip. The voltage ratings and current ratings are valid provided the other ratings are not violated.
