PRODUCTION DATA.
The voltage at FB pin is compared to an internal 0.92 V reference. If the feedback voltage rises above 0.92 V the on-time pulse is immediately terminated. This condition can occur if the input voltage, or the output load, changes suddenly. Once the OVP is activated, the buck switch remains off until the voltage at FB pin falls below 0.92 V. The low side switch will stay on to discharge the inductor energy until the inductor current decays to zero. The low side switch will be turned off.
