OCP8111A 1.0A Buck/Boost Charge Pump LED Driver

The OCP8111A is current-regulated charge pump ideal for powering high brightness LEDs for camera flash applications. The charge pump can be set to regulate two current levels for FLASH and TORCH modes. The OCP8111A automatically switches modes between step-up and step-down ensuring that LED current .

OCP8111A Features

* a very low shutdown current (less than 1uA), an automatic soft-start mode to limit inrush current, as well as over current, over voltage and over temperature shutdown control. A Low current sense reference voltage (50mV) allows the user of small 0603 current sensing resistors. The OCP8111A is of
