Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. Maximum package power dissipation must be observed.
ELECTRICAL CHARACTERISTICS (VCC and VC = 12 V [Note 2], Rref = 10 kW, CT = 820 pF, for typical values TA = 25°C,
for min/max values TA = −25° to +85°C [Note 3], unless otherwise noted.)

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