XA3106

XA3106 Synchronous Buck-Boost DC/DC Regulator Features Synchronous rectification: Up to 95% efficiency Single inductor Fixed frequency operation with battery voltages above, below or equal to the output ：Quiescent current 1mA (50uA low power mode: mode pin high) Up to 600mA continuous output current 1.8V to 5.5V input and output voltage range Programmable oscillator frequency from 350kHz to 1.5MHz No Schottky Diodes required VOUT disconnected from VIN during shutdown ＜Shutdown current: IQ 1µA Package: small thermally enhanced 10-pin MSOP Application 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 ...
