GreenChip synchronous rectier controller
[1] Voltages on pin SENSEGND less than +1.0 V will not damage the IC when the duration is limited to 100 祍, but voltages on pin
SENSEGND larger than +0.4 V may lead to disturbed IC operation.
[2] Equivalent to discharging a 100 pF capacitor through a 1.5 k& series resistor.
[3] Equivalent to discharging a 200 pF capacitor through a 0.75 礖 coil and a 10 & resistor.

Limiting values &continued
In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured with respect to power
ground (pin 2); positive currents ow 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.
