NOTES:
1. Specifications guaranteed by design & characterization and correlation with statistical process controls.
2. Specification are based upon a PFC system configured for AC input of 90-265 VAC (Sine), 45/65 Hz, Vlink= 400 V,
RAC = 3 x 1.0 MΩ, RFB = 3 x 1.0 MΩ, C3 = 180 μF, LB = 360 μH, 90 W. For other Vlink voltages, refer to Section 4
Application Example.
3. Detailed Calculation See Section 4 Application Example.
4. Overpower protection is scaled to rated power.
5. STBY is designed to be driven by an open collector. The input is internally pulled up with a 600 kΩ resistor.
6. Normal operation mode, see Section 3.2.
