Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
ELECTRICAL CHARACTERISTICS (VCC and VC = 12 V, Rref = 10 kW, CT = 2.2 nF, for typical values TA = 25°C, for
min/max values TA = −25° to +85°C unless otherwise noted.) (Note 1)

1. Adjust VCC above the startup threshold before setting to 12 V. Low duty cycle pulse techniques are used during test to maintain junction
temperature as close to ambient as possible.
2. No output signal when the Error Amplifier output is in Low State, i.e., when for instance, VFB = 2.7 V.
3. VC must be greater than 5.0 V.
