ADP1111属于升压/
Buck switching regulator系列。在升压模式下，它采用2 V至12 V输入电压工作；在降压模式下，输入电压最高可达30 V。对ADP1111进行编程，只需3个外部器件，便可在升压/降压或反相应用中工作。
Fixed outputs are 3.3 V, 5 V, and 12 V, and adjustable output models are available. In boost mode, the ADP1111 provides a 5 V, 100 mA output with a 3 V input; In buck mode, it provides a 5 V, 200 mA output with a 12 V input.
Using a resistor, the maximum switching current can be programmed to achieve it. In a variety of configurations, an open-collector gain module can be placed as a post-linear regulator, undervoltage lockout, or error amplifier for low battery level detection.
