CONFIDENTIAL

NOTES:

Specifications guaranteed by design & characterization and correlation with statistical process controls.

Specification are based upon a PFC system configured for AC input of 90-265 VAC (Sine), 45/65 Hz, Vlink=400 V,

RAC =3x1.0 MΩ, RFB =3x1.0 MΩ, C3 = 180 μF, LB = 360 μH, 90 W. For other Vlink voltages, refer to Section 4

Application Example.

Detailed Calculation See Section 4 Application Example.

Overpower protection is scaled to rated power.

STBY is designed to be driven by an open collector. The input is internally pulled up with a 600 k

Ω resistor.

Normal operation mode, see Section 3.2.
