产品概述 返回TOP
The CXLE87122 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 CXLE87122 automatically switches modes between step-up and step-down ensuring that LED current does not depend on the forward voltage. It switches at 2.2MHz, 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.
The CXLE87122 also features a very low shutdowncurrent, an automatic soft-start mode to limit inrush current, as well as over-current, over-voltage and over-temperature thermal shutdown control.
A low current-sense reference voltage (47mV) allowsthe use of small 0603 current sensing resistors.
The CXLE87122 is available in Green TDFN-3×3-10L package and is specified over an ambient temperature range of -40℃ to +85℃.
