OCP8110, 500mA Buck/Boost Charge Pump LED Driver

WWW.ORIENT-CHIP.COM OCP8110 500mA Buck/Boost Charge Pump LED Driver * General .
The OCP8110 is current-regulated charge pump ideal for powering high brightness LEDs for camera flash applications.

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 OCP8110 is offere

Applications

* The charge pump can be set to regulate two current levels for FLASH and TORCH modes. The OCP8110 automatically switches modes between step-up and step-down ensuring that LED current does not depend on the forward voltage. It switches at 1.8MHz, allowing the use of tiny components.
