AX5503-MICROPOWER VFM STEP-UP DC/DCDataSheet

GENERAL D*CRIPTION
The AX5503 is a high efficiency VFM Step-up DC/DC converter for *all, low input
voltage or battery powered systems with ultra low quiescent supply current. The AX5503 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 AX5503 combine ultra low quiescent supply current and high efficiency to give maximum battery life. The high switching frequency and the internally limited peak inductor current permits the use of *all, low cost inductors. Only three external components are needed an inductor a diode and an output capacitor.
The AX5503 is suitable to be used in battery powered equipment where low noise,low ripple and ultra low supply current are required. Operating shutdown function is outside controlling. If EN connects to GND, the IC was been shut down and than the supply current is lower to 1uA.The AX5503 is available in very *all package: SOT23-5L. T*ical applications are pagers, cameras and video camera, cellular ephones, wireless ephones, palm* computer, battery backup supplies, battery powered equipment.
