GENERAL DESCRIPTION
An external Schottky diode is needed. At light load, AP2008 works in the light load mode. Up to 2A peak current, Let AP2008 can provide 1A output load current, which is suitable to use as MID and mobile power supply. The input voltage 3V~25V.The operating frequency is internally set at 1MHz. The device is available in the small profile SOT23-6L package. 1MHz, 2A Step Up Regulator z MID and Mobile Power FEATURES
