AX5502  MICROPOWER VFM STEP-UP DC/DC Converter

性能描述：

      The AX5502 is a high efficiency VFM  Step-up DC/DC converter for *all, low input voltage or battery powered syst ems with ultra-low quiescent  supply current. The AX5502 accept a positive input voltage  from start-up voltage to VOUT  and convert it to a higher output voltage in the  2.2V to 5V range.
      The AX5502 combine ultra low quiescent supply curren t and high efficiency to give maximum battery life. The high switching frequen cy and the internally lim ited peak inductor current permits the use of *al l, low cost inductors. Only three external components are needed an inductor a diode and an output capacitor.
      The AX5502 is suitable to be used in  battery powered equipm ent where low noise,low ripple and ultra low supply current are requ ired. The AX5502 is avai lable in very *all package: SOT-23-3L, SOT-23-5L and SOT-89-3L. T*ical applications are pagers, came ras and video camera, cellular ephones, wireless ephones, palm* computer, battery backup supplies, battery powered equipment.

特点：

•  Very Low Supply Current
•  Regulated Output Voltage
•  Wide range of output voltage is available form 2.2V to 5.0V by 0.1V steps
•  Output Voltage Accuracy &plu*n;5%
•  Output Current up to 100mA
•  Low ripple and low noise
•  Very low start-up voltage
•  High efficiency (VOUT  = 5V TYP. 87%)
•  Few external components
•  Low profile: SOT-23-3L, SOT-23-5L and SOT-89-3L Pb-Free
