The MIC4682 is an easy-to-use step-down (buck) switchmode voltage regulator. It features a programmable current limit that allows 10% current limit accuracy over its full operating temperature range. The precision current limit makes the MIC4682 ideal for constant-voltage constantcurrent applications, such as simple battery chargers. The precision current limit also gives designers the ability to set the maximum output current below the saturation current rating of the inductor. This allows the use of the smallest possible inductors for a given application, saving valuable space and cost.
