*VC must be greater than 5.0 V.
1. Adjust VCC above the start–up 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.
