3. Specifications guaranteed by design & characterization.
4. Specifications measured as an instantaneous quantity NOT as a time-averaged quantity.
5. STBY is designed to be driven by an open-collector device. The input is internally pulled up with a 600 kΩ resistor.
6. The package thermal impedance is calculated in accordance with JESD 51.
7. Based upon input voltage 120 to 277 VAC and an output voltage (V_out) of 460 V, with boost inductance of 380 μH,
output capacitance of 23.5 μF, and VDD of 13 V.
