3. CHARACTERISTICS AND SPECIFICATIONS
3.1 Electrical Characteristics
Typical characteristics conditions:
T
A
= 25º C, V
DD
= 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:
T
J
= -40º to +125º C, V
DD
= 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, V
