Product data sheet Rev. 1 — 9 April 2014 6 of 13 NXP Semiconductors TEA1892TS GreenChip synchronous rectifier controller 8. Limiting values [1] Equivalent to discharging a 100 pF capacitor through a 1.5 k series resistor. 9. Thermal characteristics 10. 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.
