Typical Applications
Description
The HAMX810018 is high efficiency, fixed frequency, Buck-Boost DC/DC converters which operates from input voltages above, below or equal to the output voltage. The devices are suitable for single lithium-ion, multicell alkaline or Ni MH applications where the output voltage is within the battery voltage range.
