PRODUCTION DATA.
The feedback voltage at FB is compared to an internal 1.62 V reference. If the voltage at FB rises above 1.62-V the on-time pulse is immediately terminated. This condition can occur if the input voltage and/or the output load changes suddenly. The high-side switch will not turn on again until the voltage at FB falls below 1.225 V.
