Abstract: An example controller circuit includes a feedback sampling circuit, an oscillator, a drive logic, and a false sampling prevention circuit. The feedback sampling circuit generates a sample signal in response to a sampling of a feedback signal. The oscillator generates an on-time signal that transitions from a first logic state to a second logic state during each period of the on-time signal. The drive logic controls a switch to regulate the output of a power converter. The drive logic turns on the switch to end an off-time of the switch in response to the on-time signal transitioning from the first logic state to the second logic state. The false sampling prevention circuit prevents the on-time signal from transitioning from the first logic state to the second logic state to extend the off-time of the switch until a sampling complete signal indicates that sampling of the feedback signal is complete.

Abstract: In an example embodiment, a method of automatically generating data validation rules from data stored in a column of a table is provided. Outliers for the data are determined by analyzing a profiling statistic for the data, the profiling statistic having a type. Then it is determined if a predefined limit is exceeded, based on a quantity of the outliers determined for the data through the analysis of the profiling statistic. A data validation rule is then automatically generated based on non-outliers detected in the data through the analysis of the profiling statistic, the generated data validation rule also being based on the type of the profiling statistic. The data validation rule can then be applied to data subsequently entered for the column, causing at least a portion of the data subsequently entered for the column to be rejected.
