   产品概述 返回TOP1RL嘉泰姆

The CXLE8873 is high efficiency, fixed frequency, Buck-Boost DC/DC constant output current converter which operates from input voltages above, below or equal to the output voltage. The devices are suitable for single lithium-ion, multicell alkaline or NiMH applications where the output voltage is within the battery voltage range. Other features include a below 1μA shutdown current, thermal shutdown and current limit. 

The CXLE8873 converter is available in the 10-pin thermally enhanced DFN3*3-10L or MSOP-10L packages.
