Introduction

AI Translation

The DIO5151B is a 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 DIO5151B automatically switches modes between step-up and step-down ensuring that LED current does not depend on the forward voltage. It switches at 2MHz, allowing the use of tiny components. The supply voltage ranges from 3V 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. The DIO5151B also features a very low shutdown current, an automatic soft-start mode to limit inrush current, as well as over current, over voltage and over thermal shutdown control. A low current sense reference voltage (47mV) allows the use of small 0603 current sensing resistors. The DIO5151B is available in Green DFN22.2-8, DFN33-10 package and is specified over an ambient temperature range of -40°C to 85°C.
