PRODUCTION DATA
To prevent undesired performance under no-load and near no-load conditions, the UCC28070A zero-power detection comparator is designed to disable both GDA and GDB outputs in the event VVAO voltage falls below 0.75V. The 150mV of hysteresis ensures that the outputs remain disabled until VVAO has nearly risen back into the linear range of the multiplier (VVAO ≥ 0.9V).
