3. CHARACTERISTICS AND SPECIFICATIONS
3.1 Electrical Characteristics
Typical characteristics conditions:
TA = 25 C, VDD = 13 V, GND = 0 V
All voltages are measured with respect to GND.
Unless otherwise specified, all currents are positive when
flowing into the IC.
Minimum/Maximum characteristics conditions:
TJ = -40 to +125 C, VDD = 10 V to 15 V, GND = 0 V
Notes:
1.
Specifications guaranteed by design and are characterized and correlated using statistical process methods.
2.
Specification are based upon a PFC system configured for AC input of 90-265 VAC (Sine), 45/65 Hz, Vlink=400 V,
RIAC = 3.0 MΩ, RIFB = 3.0 MΩ, C3 = 180 μF, LB =360 μH, 90 W.
3.
Overpower protection is scaled to rated power.
4.
Normal operation mode, see 5.2 Start-up vs. Normal Operation Mode on page 8.
