PRODUCTION DATA.
The feedback voltage at FB is compared to an internal 2.875-V reference. If the voltage at FB rises above 2.875 V, the on-time pulse is immediately terminated. This condition can occur if the input voltage or the output load change suddenly. The buck switch does not turn on again until the voltage at FB falls below 2.5 V.
