THERMAL CHARACTERISTICS
Note
1. Pins GND1, GND2, GND3 and GND4 connected to sufficient copper area on the printed-circuit board.
CHARACTERISTICS
Vin = 330 V; VAT = 36 V; RRref =31k; Tamb =25 °C; IC not in current foldback mode; no over-voltage;
no over-temperature; unless otherwise specied. All voltages are measured with respect to ground; currents are
positive when owing into the IC.
