OCP8110A - 500mA Buck/Boost Charge Pump LED Driver

General Description

The OCP8110A 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.

Key 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 OCP8110A is o.

WWW.ORIENT-CHIP.COM OCP8110A 500mA Buck/Boost Charge Pump LED Driver ◼ General Description The OCP8110A 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 OCP8110A 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. The supply voltage ranges from 2.7V to 5.5V and is ideally suited for all applications powered by a single Li_Ion battery cell or three to four NiCd, NiMH, or Alkaline battery cells.
