Description
The XA3106 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 NiMH applications where the output voltage is within the battery voltage range.
The switching frequencies up to 1.5 MHz could be fixed by employing an external resistor, and the oscillator could be ...
