TEA1791T
GreenChip synchronous rectifier controller
8. Limiting values
[1] Equivalent to discharging a 100 pF capacitor through a 1.5 k?series resistor.
[2] Equivalent to discharging a 200 pF capacitor through a 0.75 糎 coil and a 10 ?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.
