Kingbor Technology Co.,Ltd TEL:(86)0755-26508846 FAX:(86)0755-26509052 KB3386 .
The KB3386 is a current regulated charge pump ideal for powering high brightness LEDs for camera flash applications.

Features

* Output Current up to 400mA
* Up to 94% Efficiency in Torch Mode
* Automatic Softstart Limits Inrush Current
* Adjustable FLASH Mode
* x1 and x2 Automatic Modes for High Efficiency www. DataSheet4U. com
* Minimum External Components: No Inductors
* High Frequency Operation

Applications

* The charge pump can be set to regulate two current levels for FLASH and TORCH modes. The KB3386 automatically switches modes between step-up and step-down ensuring that LED current does not depend on the forward voltage. A low current sense reference voltage (50mV) allows the use of small 0603 curr
