Abstract
Apparatus and methods for boost regulators with dynamic regulation band are disclosed. In certain configurations, a boost regulator system includes a boost regulator, a current source, and a light emitting element, such as a flash LED, that is controlled using a current generated by the current source. The boost regulator generates an output voltage that is used to power the current source. The boost regulator operates with a regulation band that changes based on a current level of the light emitting element.
