ADP2503 Product Details

During logic-controlled shutdown, the input is disconnected from the output and draws less than 1 μA from the input source. Operating as boost converters, the ADP2503/ADP2504 feature a true load disconnect function that isolates the load from the power source. Other key features include undervoltage lockout to prevent deep battery discharge, and soft start to prevent input current overshoot at startup.
