Abstract
A motorized hand tool, such as a cordless ratchet wrench, that has a motor, one or more electronic components and/or integrated circuits, and a step-up converter that are housed or disposed in a housing of the tool. The step-up converter is adapted to prevent a voltage of a battery of the tool from dropping below a threshold voltage of a component or integrated circuit when current draw from the battery increases, thus preventing a 'brownout' condition.
