NOTES: 1. Adjust VCC above the start threshold before setting at 10 V.
2. Oscillator frequency for the UCC2800, UCC2802, and UCC2803 is the output frequency.
Oscillator frequency for the UCC2801, UCC2804, and UCC2805 is twice the output frequency.
3. Gain is defined by:
A = D
VCOMP
DVCS
0 v VCS v 0.8 V
4. Parameter measured at trip point of latch with Pin 2 at 0 V
5. Total variation includes temperature stability and load regulation.
6. Start threshold, stop threshold, and zener shunt thresholds track one another.
7. Not production tested
8. The device is fully operating in clamp mode as the forcing current is higher than the normal operating supply current.
